FlowTrem2 Setup and Care: Balance, Action, Intonation and Maintenance

A correctly installed FlowTrem2 is not automatically fully set up. Installation establishes the mechanical system; setup brings string tension, spring tension, bridge position, neck relief, action, radius, intonation and locking into a stable working relationship.

The correct sequence matters because these adjustments influence one another. Final intonation and return-to-pitch evaluation belong near the end, after the intended strings, tuning, balance and action are established.

Setup Foundations

Scope of This Guide

This guide covers:

• Selecting the intended string gauge and tuning
• Establishing the neutral bridge position
• Balancing string and spring tension
• Setting the fine tuners
• Tuning and locking the system
• Checking neck relief
• Setting bridge height and action
• Verifying the resulting string radius
• Setting intonation
• Testing return to pitch
• Changing strings
• Cleaning and maintaining FlowTrem2
• Identifying common setup problems

This guide assumes that:

• FlowTrem2 is mechanically compatible with the guitar.
• Both knife edges are seated correctly.
• The pivot studs and inserts are secure.
• The correct MONOLITH block has been installed.
• The block clears the cavity.
• The springs and spring claw are installed correctly.
• The locking nut is compatible and secure.
• The complete movement path has already been checked.

If any of these conditions is uncertain, return to the FlowTrem2 Installation Guide before continuing.

The Central Setup Principle

A freely floating double-locking tremolo is held between two opposing forces.

String Tension

Pulls the bridge toward the neck.

Spring Tension

Pulls the bridge toward the rear cavity.

The neutral bridge position is reached when these forces are in balance.

Changing any part of the string system changes that balance.

This includes:

• Changing string gauge
• Changing tuning
• Replacing one string
• Tuning one string
• Changing scale tension
• Adjusting the spring claw
• Changing the number of springs
• Changing spring type

This is why tuning one string can temporarily change the pitch of the others.

It is normal behavior for a floating tremolo.

Floating, Decked and Dive-Only Setups

FlowTrem2 can operate within different guitar configurations.

Fully Floating

The bridge can move:

• Downward to lower pitch
• Upward to raise pitch

The neutral position is established by string-to-spring balance.

Decked

The bridge rests against the guitar body or a defined supporting surface.

The body prevents upward movement beyond the neutral position.

Dive-Only

A mechanical stop prevents pull-up movement while downward movement remains possible.

Fully Blocked

The tremolo is immobilized in both directions and behaves mechanically more like a fixed bridge.

The correct setup procedure depends on the actual configuration.

Instructions concerning a level floating bridge do not automatically apply to a deliberately decked or blocked system.

The Neutral Position

For a conventional recessed floating installation, the intended starting reference is normally a baseplate positioned parallel to the guitar’s intended tremolo reference plane.

On a flat-top guitar, this is often visually close to parallel with the top surface.

On a guitar with:

• A carved top
• An angled route
• A top-mounted bridge
• A deliberately decked system
• A mechanical tremolo stop

the visible guitar surface may not be the correct reference.

The route and bridge geometry determine the intended neutral position.

Why the Neutral Position Matters

The neutral position influences:

• Available dive range
• Available pull-up range
• Action
• Intonation
• Spring feel
• Fine-tuner relationship
• Return to pitch
• Block clearance
• Saddle and screw clearance

A bridge that sits too far forward may:

• Raise the action
• Reduce dive range
• Increase pull-up range
• Contact the route
• Change intonation
• Feel unusually soft

A bridge that sits too far back may:

• Lower the action
• Reduce pull-up range
• Increase dive range
• Contact the cavity
• Create fret buzz
• Change intonation
• Feel unusually stiff

Bridge angle should be corrected before final action and intonation.

Select the Final String Set First

Complete the setup with the exact string set intended for normal use.

Confirm:

• Number of strings
• Individual string gauges
• Plain or wound third string
• Tuning
• Scale length
• Intended pitch range

A setup performed with one string set is not automatically valid for another.

Changing from a light set to a heavier set normally increases total string tension.

Changing to a lower tuning normally reduces it.

Either change affects the neutral bridge position.

Use Stable Strings

New strings must be:

• Installed correctly
• Locked securely at the bridge
• Brought gradually to pitch
• Stretched carefully
• Retuned repeatedly

Do not finalize:

• Spring balance
• Nut locking
• Action
• Intonation
• Return-to-pitch assessment

while the strings are still settling significantly.

Recommended Setup Order

A practical FlowTrem2 setup sequence is:

1. Install the intended string set.
2. Establish usable fine-tuner positions.
3. Tune with the locking nut released.
4. Stretch and stabilize the strings.
5. Balance the bridge through the spring claw.
6. Check neck relief.
7. Set bridge height and action.
8. Recheck bridge balance.
9. Measure the resulting string radius.
10. Set intonation.
11. Lock the nut.
12. Fine-tune.
13. Test the complete tremolo movement.
14. Check return to pitch.
15. Recheck pickup and cavity clearance.
16. Perform a complete playing test.

These adjustments influence one another.

Final intonation should come near the end of the process.

Initial Tuning and Fine-Tuner Range

Preparing the FlowTrem2 Fine Tuners

FlowTrem2 uses a direct relationship between the fine-tuner screw, locking screw, saddle and baseplate rather than the conventional permanent Floyd Rose Fine Tuner Tension Plate architecture.

Before coarse tuning, place each fine tuner in a useful working range with adjustment available in both directions. The fine-tuner tip must remain able to engage the corresponding locking screw through its usable travel.

Fully turning the fine tuners down so they temporarily support the saddles during a string change is optional. It can be convenient for players accustomed to saddles that remain supported when string tension is removed, but FlowTrem2 does not require this procedure.

Why Contact Matters

A fine tuner that does not engage its locking screw cannot control the saddle correctly.

Possible symptoms include:

• Delayed fine-tuner response
• Dead travel
• Uneven adjustment
• Mechanical noise
• Limited correction range
• Inconsistent return

Do not add a conventional Fine Tuner Tension Plate merely to compensate for incorrect fine-tuner contact.

Standard FlowTrem2 omits the permanent Fine Tuner Tension Plate. Where the documented optional conventional plate configuration is deliberately used, install it only with the dedicated KMS Fine Tuner Spring Plate Support Sheet. The plate restores unloaded upward preload on the String Locking Screws and does not change normal saddle geometry, but the added approximately 1.5 mm underside stack changes effective block reach. Recheck MONOLITH selection and cavity clearance before finalizing the setup.

Release the Locking Nut

Before coarse tuning:

• Loosen all locking-nut clamps.
• Confirm that the strings can move normally through the nut.
• Keep the clamps and screws organized.
• Inspect the clamping surfaces for debris or damage.

Do not attempt major tuning changes while the nut remains locked.

The fine tuners are intended for small pitch corrections after the coarse tuning has been established.

Initial Tuning

Tune the guitar using the machine heads.

Work progressively across the entire string set.

A practical method is:

1. Bring all strings gradually toward pitch.
2. Return to the first string.
3. Correct the complete set again.
4. Repeat until the strings remain close to the intended tuning.
5. Check the bridge position.
6. Correct the spring balance where required.
7. Tune the complete set again.

Several passes are normal.

Why the Other Strings Move

When one string is tightened, it pulls the floating bridge forward slightly.

This reduces the tension of the other strings.

When one string is loosened, the bridge moves back and the other strings may rise in pitch.

The effect becomes smaller as the system approaches equilibrium.

It does not indicate that the strings or tuners are defective.

Using a Setup Block

A setup block can hold the bridge close to its intended neutral position while:

• Installing strings
• Changing string gauge
• Establishing tuning
• Adjusting the claw
• Setting intonation
• Performing maintenance

The block should:

• Be stable
• Be finish-safe
• Contact suitable surfaces
• Avoid damaging the baseplate
• Hold the bridge without excessive force

When string and spring forces are correctly balanced, the block should become lightly loaded or removable without force.

Do not pull a heavily trapped block from the loaded system.

Bridge Balance and Springs

Balancing the Bridge

Inspect the baseplate from the side.

For a conventional floating setup:

Bridge Tilts Forward

The string tension exceeds the spring tension.

Increase spring tension by tightening the spring-claw screws.

Bridge Tilts Backward

The spring tension exceeds the string tension.

Reduce spring tension by loosening the spring-claw screws.

Make small adjustments.

After every change:

1. Retune every string.
2. Recheck the baseplate position.
3. Repeat until the bridge and tuning remain stable together.

Adjust the Claw Evenly

Normally, both spring-claw screws should be adjusted in similar increments.

This supports:

• Stable claw alignment
• Even screw engagement
• Centered spring loading
• Predictable adjustment

Do not create a heavily angled claw merely to correct a problem that has not been identified.

A slight deliberate difference may be used in a product-specific setup, but it should not be the default response to an unstable bridge.

Spring Number and Arrangement

The required spring configuration depends on:

• String count
• String gauges
• Tuning
• Scale length
• Spring strength
• Desired arm feel
• Available claw adjustment

Possible configurations include:

• Two springs
• Three parallel springs
• Three angled springs
• Four springs
• Five springs

A light six-string set may require less spring force than:

• A heavy six-string set
• A low tuning
• A seven-string set
• A long-scale instrument

There is no universal correct spring number.

More Springs Do Not Automatically Mean a Stiffer Arm

The final feel depends on the complete combination of:

• Number of springs
• Individual spring rate
• Spring extension
• Claw position
• String tension
• Tremolo geometry

Adding a spring and reducing its extension can sometimes produce another feel from using fewer highly stretched springs.

The complete system must be evaluated rather than the spring count alone.

Symmetrical Spring Loading

A symmetrical spring arrangement is a reliable starting point.

It helps keep the spring force centered on the MONOLITH block.

Check that:

• Every spring is fully engaged.
• No spring rubs against the cavity wall.
• Springs do not interfere with wiring.
• Spring hooks are not damaged.
• The claw remains secure.
• The block remains free throughout its travel.

Spring Noise

Springs can produce audible mechanical resonance.

Possible approaches include:

• Verifying correct spring seating
• Checking for cavity contact
• Repositioning wiring
• Using a suitable approved damping method
• Replacing damaged springs

Do not pack the cavity with material that restricts tremolo movement or traps moisture.

Locking and Fine Tuning

Locking the Nut

Lock the nut only after:

• The intended tuning is stable.
• The bridge is in its correct neutral position.
• The strings have been stretched.
• No major action adjustment remains.
• The fine tuners have useful range.

Tighten the nut clamps evenly and securely.

Do not use excessive force.

After locking, correct small tuning differences with the FlowTrem2 fine tuners.

Fine-Tuning After Nut Locking

Check each string with an accurate tuner.

Make small corrections.

When a fine tuner reaches the end of its range:

1. Unlock the nut.
2. Return all fine tuners to useful working positions.
3. Tune with the machine heads.
4. Recheck bridge balance.
5. Lock the nut again.
6. Complete the tuning with the fine tuners.

Do not continue forcing a fine tuner that has reached its mechanical limit.

Relief, Action and Clearance

Check Neck Relief Before Final Action

Neck relief is the controlled longitudinal curvature of the neck under string tension.

It influences fret clearance throughout the fingerboard.

An unsuitable neck condition can cause:

• Excessive action
• Lower-fret buzzing
• Middle-fret buzzing
• Choking during bends
• Uneven playing feel
• Misleading bridge-height adjustments

Do not use the FlowTrem2 pivot studs to compensate for an incorrectly adjusted neck.

The correct sequence is:

1. Install and tune the intended strings.
2. Balance the tremolo.
3. Evaluate neck relief.
4. Adjust the neck where required.
5. Rebalance and retune.
6. Set final bridge height.

Truss-rod adjustment should be performed carefully.

When the neck condition, truss-rod response or fret condition is uncertain, consult a qualified guitar technician.

Setting Bridge Height

FlowTrem2 action is adjusted through the two pivot studs.

Raising both studs raises the bridge.

Lowering both studs lowers the bridge.

Bass and treble sides can be adjusted independently where the guitar setup requires different string heights.

The bridge does not need to appear visually level from bass to treble.

It must provide the correct resulting string action.

Adjusting the Pivot Studs

Use the correct tool and protect the stud sockets.

For substantial height changes:

• Reduce string and spring load.
• Support the bridge.
• Make small controlled adjustments.
• Confirm that the knife edges remain seated correctly.
• Retune and rebalance afterward.

Small final corrections may be made according to the confirmed KMS procedure, but the studs should never be forced while:

• The bridge is binding
• An insert is moving
• The stud thread is damaged
• The tool does not fit
• The knife edge is incorrectly seated

Do not grip the studs with pliers.

Measure the Resulting Action

String action is normally measured from:

• The top of the fret
• To the underside of the string

The 12th fret is a common reference point.

Measure at least:

• Lowest string
• Highest string

Additional measurements across the string set can help identify an unsuitable radius.

There is no universal action value for every FlowTrem2 guitar.

The correct action depends on:

• Neck relief
• Fret condition
• Fretboard radius
• String gauge
• Tuning
• Scale length
• Picking force
• Bending requirements
• Player preference

Low Action

Lower action can provide:

• Reduced fretting effort
• Fast playing feel
• Easier legato

It can also increase the risk of:

• Fret buzz
• Choking during bends
• Reduced dynamic headroom
• Contact during strong picking

Higher Action

Higher action can provide:

• Greater fret clearance
• More dynamic headroom
• Stronger bending clearance

It can also increase:

• Fretting force
• Pitch sharpening from finger pressure
• Playing effort

The setup should be selected for actual playing conditions rather than for the lowest possible measurement.

Recheck Bridge Balance After Height Changes

Changing pivot height can slightly alter:

• String tension
• Scale geometry
• Neutral bridge position
• Action
• Intonation

After adjusting the studs:

1. Tune the guitar.
2. Check the neutral bridge position.
3. Correct spring balance where required.
4. Measure the action again.

Pickup Clearance

FlowTrem2 changes the vertical and horizontal position of the strings during tremolo use.

Check pickup clearance during:

• Normal playing
• Full practical dive
• Available pull-up
• Strong picking

Pickup height should be finalized after the string action is established.

Excessively high pickups can cause:

• Physical string contact
• Uneven output
• Magnetic influence on string vibration
• Restricted tremolo travel

FlowTrem2 Radius

The FlowTrem2 Saddle Architecture

Conventional Floyd Rose systems use stepped saddle heights and may use shims to establish another radius.

FlowTrem2 saddles follow a different principle.

The string settles into precision V geometry.

A thicker string sits differently within the V from a thinner string.

This allows the actual string diameters to contribute to the final string-height relationship.

The distinction is not that conventional Floyd-style saddles normally require filing; they do not. The difference is that their rounded string grooves support strings of different gauges at essentially the same height, while the FlowTrem2 geometry creates gauge-dependent support height as part of the complete saddle architecture.

Do Not Modify the FlowTrem2 Saddles

Do not:

• Cut a conventional slot into the V
• Deepen the contact area
• Round the V
• Reshape the saddle
• Polish away the functional geometry
• Abrade or modify a coated contact surface

The complete FlowTrem2 saddle geometry is a finished functional system. The V-shaped contact must not be altered.

Filing it would permanently change:

• String centering
• String height
• Contact geometry
• Radius
• Gauge flexibility
• Surface performance

Do Not Transfer Conventional Radius Shims Automatically

Standard Floyd Rose instructions may use:

• A factory radius shim
• Individual saddle shims
• Different saddle-height combinations

These instructions apply to conventional Floyd Rose saddle architecture.

Do not add conventional Floyd Rose radius shims or improvised saddle shims to FlowTrem2 unless a specific KMS configuration explicitly requires them.

FlowTrem2 must be evaluated through its own saddle geometry.

Measure the Strings, Not Only the Saddles

The visible saddle tops do not represent the final playing radius.

Measure the actual string surfaces.

Use an appropriate radius gauge beneath the strings where possible.

Check the radius after:

• Final string gauge is installed
• Bridge height is set
• Neck relief is correct
• Tremolo balance is stable

Fretboard Radius and String Radius Are Related, Not Always Identical

The final string radius may need to account for:

• Fretboard radius
• Compound radius
• Bass-to-treble action difference
• String diameter
• Bending clearance
• Player preference

A compound-radius neck often requires a flatter string radius at the bridge than at the nut.

The correct bridge result follows the extended geometry of the fingerboard rather than copying the nut radius.

Seven-String FlowTrem2

On seven-string guitars, verify:

• Complete string radius
• Outer-string fretboard clearance
• Low-string height
• Pickup alignment
• Saddle centering
• Locking-nut spacing

FlowTrem2 saddle geometry can accommodate broad practical gauge ranges without individually filed slots.

The exact setup must still be measured using the intended strings.

A heavy low string can sit higher within the V than a thinner string.

This is part of the geometry, not necessarily a setup error.

Keep the Bridge Mechanically Level

Do not deliberately twist the complete bridge to correct one individual string.

The two pivot studs control the overall bass and treble height.

Individual string relationships come from:

• Saddle geometry
• String diameter
• Product configuration

Both studs should remain correctly engaged and the baseplate should remain free to pivot without distortion.

Intonation

Intonation adjusts the effective vibrating length of each string.

When a string is fretted, it is stretched slightly.

Without compensation, the fretted note can become sharp.

The required compensation depends on:

• String gauge
• Core construction
• Winding
• Action
• Fret height
• Tuning
• Scale length
• Fretting pressure

Each FlowTrem2 saddle can be positioned individually.

Prepare the Guitar Before Intonation

Set intonation only after:

• The intended strings are installed.
• The strings are stable.
• The guitar is at the intended tuning.
• Neck relief is correct.
• Action is established.
• Bridge balance is stable.
• The neutral position is correct.
• Saddles and locking components are secure.

Changing action or bridge angle afterward can alter the result.

Unlock the Nut

Release the locking-nut clamps before setting intonation.

This allows the guitar to be retuned through the machine heads after every saddle adjustment.

Return the fine tuners to useful working positions where necessary.

Compare the Octave

For each string:

1. Tune the open string accurately.
2. Check the 12th-fret harmonic as an octave reference.
3. Fret the note at the 12th fret with normal playing pressure.
4. Compare the fretted pitch with the octave reference.
5. Determine whether the fretted note is sharp or flat.

Use consistent finger pressure.

Excessive pressure can sharpen the fretted note and produce a misleading result.

Adjustment Direction

Fretted Note Is Sharp

The effective vibrating string length is too short.

Move the saddle away from the nut.

Fretted Note Is Flat

The effective vibrating string length is too long.

Move the saddle toward the nut.

Retune after every adjustment.

Moving a FlowTrem2 Saddle

Before moving a saddle:

1. Identify the required direction.
2. Detune the string until it is substantially slack.
3. Support or hold the saddle where required.
4. Loosen the saddle mounting screw with the correct tool.
5. Move the saddle by a small controlled amount.
6. Confirm that it remains square and fully seated.
7. Tighten the mounting screw securely.
8. Retune the string.
9. Recheck the octave.

Do not slide a loaded saddle across the baseplate under full string tension.

Saddle Mounting Screw Position

Original-style tremolo baseplates may provide more than one saddle-mounting position to extend the usable adjustment range.

Use only positions provided and approved for the actual FlowTrem2 version.

Do not:

• Drill another hole
• Enlarge an existing hole
• Shorten the saddle
• Modify the baseplate
• Use an incorrect screw
• Force the saddle against the baseplate bend

Extended FlowTrem2 Intonation Range

FlowTrem2 modifies the baseplate architecture to provide approximately 2 mm of additional useful intonation range compared with the conventional Floyd Rose Original reference.

This additional range can help with:

• Heavy string gauges
• Lower tunings
• Seven-string applications
• Guitar-specific scale tolerances
• Saddles positioned near the conventional limit

It does not correct:

• Incorrect pivot placement
• Wrong scale length
• Incompatible installation geometry
• Excessive action
• A defective string
• Incorrect saddle mounting

Additional range remains part of a correctly positioned system.

Adjust in Small Steps

A small saddle movement can create a measurable pitch change.

Work progressively.

Do not attempt to predict the entire final position from the first measurement.

A useful cycle is:

1. Measure.
2. Detune.
3. Move.
4. Secure.
5. Retune.
6. Measure again.

Use a Stable Playing Position

Where practical, check intonation with the guitar held in its normal playing orientation.

Neck support and gravity can slightly affect a sensitive setup.

Use the same:

• Tuner
• Picking strength
• Fretting pressure
• Reference method

for every string.

Do Not Set Intonation by Saddle Appearance

A familiar visual staircase is common.

It is not the objective.

The final pattern depends on:

• String construction
• Gauge
• Plain or wound third string
• Tuning
• Scale
• Player pressure

A visually unusual saddle arrangement can be correct.

A visually perfect staircase can be incorrectly intonated.

When a Saddle Reaches Its Limit

Before modifying anything, check:

• Bridge orientation
• Neutral bridge position
• String gauge
• Intended tuning
• String condition
• Neck relief
• Action
• Pivot location
• Saddle mounting position
• Scale length

A defective or twisted string can also create an intonation result that cannot be stabilized.

Replace the string before diagnosing a structural problem.

Secure Every Saddle

After intonation, verify that every saddle mounting screw is secure.

A loose saddle can cause:

• Intonation drift
• Mechanical noise
• Unstable string contact
• Poor return
• Movement during tremolo use

Secure does not mean overtightened.

Use the correct tool and controlled hand force.

Rebalance After Intonation

Saddle movement changes the effective string length and can slightly affect the force balance.

After setting all strings:

1. Tune the complete guitar.
2. Check the bridge neutral position.
3. Correct spring tension if required.
4. Recheck intonation.
5. Lock the nut only after the complete system is stable.

Final Nut Locking

Once intonation and tuning are stable:

• Confirm usable fine-tuner travel.
• Tighten the nut clamps evenly.
• Fine-tune the guitar.
• Perform another octave check.

Locking the nut should not substantially change the intonation setting.

A significant pitch shift can indicate:

• String movement during clamping
• Incorrect nut seating
• Uneven clamp pressure
• A setup that was not stable before locking

Return-to-Pitch Validation

Return-to-Pitch Testing

A double-locking tremolo should return consistently toward its established neutral position after normal use.

Test the system only after:

• Strings are stable
• Nut clamps are secure
• Bridge string locks are secure
• Spring balance is correct
• Saddles are secure
• Studs and inserts are stable
• All movement clearances have been confirmed

Progressive Movement Test

Do not begin with maximum arm travel.

Use this sequence:

1. Apply light vibrato.
2. Release the arm naturally.
3. Check tuning.
4. Perform a moderate dive.
5. Release and check tuning.
6. Perform a moderate pull-up where available.
7. Release and check tuning.
8. Repeat several times.
9. Test greater travel only after the system behaves consistently.

Release the Arm Naturally

Do not force the bridge toward a visually estimated center position.

Allow the knife edges, strings and springs to return the bridge.

Pushing the arm into position can temporarily conceal a setup problem.

Check Dive and Pull-Up Separately

A system can return differently after:

• Lowering pitch
• Raising pitch

This difference can help identify:

• Pivot friction
• Contact with the route
• Spring interference
• Nut or string-lock movement
• Loose hardware
• Unstable inserts

Record whether the guitar returns:

• Sharp after a dive
• Flat after a dive
• Sharp after a pull-up
• Flat after a pull-up
• Differently on one string only
• Differently across all strings

The pattern provides useful diagnostic information.

All Strings Shift Together

When all strings move in a similar direction, inspect system-wide causes such as:

• Bridge angle
• Knife-edge seating
• Pivot studs
• Stud inserts
• Spring balance
• Spring contact
• Cavity contact
• Locking-nut attachment
• Complete bridge movement

One String Moves Differently

When one string behaves differently, inspect:

• Bridge string lock
• Locking insert
• String end
• Nut clamp
• Saddle security
• String damage
• Fine-tuner contact
• Machine-head winding before locking

A single-string problem is less likely to originate from the complete spring balance.

Check the Locking Nut

Confirm:

• Nut body is secure
• Mounting screws are secure
• Clamp blocks are seated correctly
• Clamp screws are secure
• Strings are cleanly captured
• No debris lies beneath the clamps
• Threads are undamaged

A locking nut that moves on the neck can prevent stable return even when the bridge itself is functioning correctly.

Check the Bridge Locks

Confirm that every string:

• Is inserted fully
• Is clamped by the correct insert
• Has not slipped
• Has no crushed or frayed end
• Remains centered in the FlowTrem2 saddle

Do not respond to repeated slipping only by applying greater force.

Inspect the insert, screw and string end.

Check the Saddle Mounting Screws

A loose saddle can move during arm use.

Verify:

• Full saddle seating
• Correct screw
• Secure mounting
• No debris below the saddle
• No damaged thread
• Correct intonation position

Check the Knife Edges and Studs

The knife edges must:

• Sit correctly in both stud grooves
• Remain free from visible damage
• Pivot without body contact
• Return without binding

The studs must remain:

• Straight
• Stable
• Correctly aligned
• Secure in their inserts

Do not attempt to sharpen or file a FlowTrem2 knife edge during routine maintenance.

Damage should be assessed professionally.

Check the Complete Movement Envelope

Inspect the bridge while operating it.

Look for contact involving:

• Locking screws
• Saddle screws
• Baseplate
• Fine tuners
• OmniPort
• MONOLITH block
• Springs
• Cavity walls
• Rear cover
• Wiring
• Pickup

A system can clear the guitar at rest and still bind during movement.

Troubleshooting

Spring and Claw Problems

Inspect for:

• Spring rubbing
• Damaged spring hooks
• Loose claw screws
• Moving claw
• Uneven spring engagement
• Wiring touching springs
• Insufficient screw engagement
• Cavity obstruction

Spring noise alone does not always cause tuning instability.

Physical restriction of the spring or block can.

Fine Tuner Has No Effect

Possible causes include:

• No contact with the locking screw
• Fine tuner outside its usable range
• Damaged thread
• Incorrect locking screw position
• Contamination
• Incompatible component
• Mechanical obstruction

Re-establish the intended direct contact before further diagnosis.

Fine Tuner Reaches Its Limit

Unlock the nut and reset the complete coarse tuning.

Do not force the fine tuner farther.

The correct procedure is:

1. Unlock the nut.
2. Return fine tuners to useful positions.
3. Tune through the machine heads.
4. Check bridge balance.
5. Lock the nut.
6. Fine-tune.

Bridge Tilts Forward Repeatedly

Possible causes include:

• Higher string tension than the previous setup
• Lower spring force
• Insufficient claw engagement
• Missing or weak spring
• Changed tuning
• Spring not seated correctly

Bridge Tilts Backward Repeatedly

Possible causes include:

• Lower string tension
• Excessive spring force
• Additional spring
• Claw positioned too far inward
• Broken or slipping string
• Lower tuning

String Breakage at the Saddle

Repeated breakage at the same position can indicate:

• Damaged V geometry
• Burr
• Contamination
• Surface damage
• Incorrect string path
• Excessive local wear
• Damaged locking insert

Do not file or reshape the FlowTrem2 saddle as a first response.

Inspect the precise break location.

Mechanical Noise

Possible sources include:

• Loose saddle mounting screw
• Loose locking screw
• Fine tuner without stable contact
• Spring resonance
• Spring contact
• Loose claw
• Loose stud insert
• FlowBar or OmniPort component
• Cavity cover
• Wiring
• Pickup or mounting hardware

Locate the noise mechanically.

Do not assume that it is caused by titanium or by the tremolo block.

Floating-Tremolo Behavior During String Bending

On a fully floating system, bending one string increases total string tension and pulls the bridge forward slightly.

The unbent strings can therefore become slightly flatter.

This is normal.

A dive-only, decked or blocked configuration can reduce or eliminate this behavior, but also changes the available tremolo functions.

String Changes

Changing Strings

There are two main approaches.

One String at a Time

This keeps the system closer to its established balance.

It is useful when:

• The gauge remains unchanged.
• The tuning remains unchanged.
• No complete bridge cleaning is required.
• The existing setup should be preserved.

Removing All Strings

This provides better access for:

• Cleaning
• Inspection
• Saddle work
• Pickup access
• Complete string-set changes

A floating bridge should be supported with a suitable setup block before all string tension is removed.

One-String-at-a-Time Procedure

For each string:

1. Unlock the corresponding nut clamp.
2. Detune the string.
3. Release the bridge locking screw.
4. Remove the string.
5. Inspect the locking insert.
6. Install the replacement string.
7. Clamp it securely at the bridge.
8. Tune through the machine head.
9. Stretch and retune.
10. Continue with the next string.

After all strings have been replaced:

• Tune the complete set repeatedly.
• Check bridge balance.
• Lock the nut.
• Fine-tune.
• Check intonation.

Complete String Removal

Before removing all strings:

• Support the bridge.
• Document the spring and saddle configuration.
• Release the nut clamps.
• Reduce tension gradually.
• Prevent the bridge from falling from the studs.
• Protect the guitar top and cavity edges.

Do not remove the tremolo springs unless bridge removal is required.

Optional Fine-Tuner Support During String Changes

During restringing, the fine tuners may be turned fully down so their tips temporarily support the locking screws and stabilize the saddles while string tension is removed. This is optional and not required for normal FlowTrem2 string changing.

Before final tuning, return the fine tuners to a useful working range with adjustment available in both directions.

Inspect the Locking Inserts

During every string change, inspect each insert for:

• Deep deformation
• Cracks
• Chipping
• Contamination
• Incorrect orientation
• Uneven contact

Replace a damaged insert with the correct KMS component.

Do not substitute an insert of unknown geometry or material.

Clean the String Ends

Cut the string ends cleanly.

Avoid:

• Frayed windings
• Sharp bends
• Crushed ends
• Excessive exposed core
• Dirty or corroded sections

The string should enter the saddle lock:

• Straight
• Fully
• Centrally

Do Not Overtighten

String locking requires secure clamping.

Excessive force can damage:

• String
• Insert
• Locking screw
• Saddle thread
• Tool socket

Use a correctly fitting tool and controlled hand pressure.

Cleaning and Maintenance

Cleaning FlowTrem2

For routine cleaning:

• Use a clean soft cloth.
• Remove sweat after playing.
• Remove dust from recesses carefully.
• Keep strings and contact areas clean.
• Use minimal moisture where necessary.
• Dry the component afterward.

Do not allow liquid to collect in:

• Saddles
• Fine tuners
• Screw sockets
• OmniPort
• Spring cavity
• Stud inserts

Natural Titanium

Natural Grade 5 titanium provides strong corrosion resistance.

Its appearance can still change through:

• Fingerprints
• Skin oils
• Fine scratches
• Tool contact
• Polishing through use

Normal cleaning should preserve the manufactured surface rather than attempting to polish it into another finish.

PVD, DLC and Colored Surfaces

Coated components should be cleaned gently.

Avoid:

• Abrasive polish
• Metal polish
• Steel wool
• Scouring pads
• Aggressive solvents
• Acidic cleaners
• Repeated hard rubbing

A hard functional coating can still be scratched or damaged by inappropriate tools.

Decorative color and wear resistance are separate properties.

Anodized Titanium

Anodized titanium color is created through an oxide-layer interference effect.

Finger oils and residue can temporarily change its visible color.

Use:

• A soft clean cloth
• Minimal moisture
• Gentle drying

Do not use abrasive polish to restore the color.

Abrasion changes the oxide surface itself.

FlowTrem2 Saddle Care

Keep the string-contact geometry clean.

Do not:

• File the V
• Use abrasive cord
• Polish the contact mechanically
• Apply an unknown coating
• Use aggressive solvent
• Scrape a coated contact surface

When a contact problem is suspected, inspect it under good light and consult KMS before modifying the saddle.

OmniPort and FlowBar Care

Inspect periodically:

• FlowBar surface
• O-rings
• Socket
• Cap
• Retaining clip
• M3 fastener

The O-rings should remain:

• Present
• Clean
• Undamaged
• Correctly seated

Do not attempt to adjust arm resistance by bending the FlowBar.

Do not apply oils, grease or solvents unless they are specifically approved for the OmniPort and its O-ring material.

Replace damaged O-rings with the correct KMS specification.

FlowBar Removal and Transport

For transport, removing the FlowBar can prevent it from acting as a lever against the bridge or guitar case.

Store it where:

• The surface cannot be scratched.
• The O-rings are protected.
• It cannot damage the guitar.
• It remains clean.

Do not place pressure on an installed arm when closing a case.

Knife-Edge Care

Knife edges are precision pivot surfaces.

Do not:

• File them
• Sharpen them
• Polish them with abrasive material
• Strike them against the studs
• Use the bridge as a lever
• Adjust against obvious binding

When wear or damage is suspected, remove the load and inspect the component professionally.

Pivot Studs and Inserts

Periodically check for:

• Stud movement
• Insert movement
• Tilting
• Damaged sockets
• Corrosion
• Cracks in the surrounding finish
• Unequal seating

Do not apply thread-locking compound without KMS or guitar-manufacturer approval.

The studs must remain adjustable and serviceable.

Springs and Spring Claw

Inspect:

• Spring hooks
• Spring corrosion
• Claw attachment
• Claw screws
• Ground wire
• Cavity contact
• Wiring position

Replace a damaged or heavily corroded spring.

Do not continue tightening claw screws when:

• Screw engagement is insufficient
• Wood is damaged
• The claw is moving
• The required spring force cannot be reached safely

Use another appropriate spring configuration instead.

Periodic Fastener Check

Check periodically that:

• Saddle mounting screws remain secure.
• Locking screws operate correctly.
• Fine tuners remain engaged.
• Block screws remain secure.
• OmniPort hardware remains secure.
• Nut hardware remains secure.
• Studs and inserts remain stable.

Do not perform routine overtightening.

Inspect first and tighten only where required.

Avoid Unapproved Thread Lubricants

Different FlowTrem2 components may combine:

• Titanium
• Coatings
• O-rings
• Steel
• Other product-specific materials

An inappropriate lubricant can:

• Attract contamination
• Affect friction
• damage elastomers
• Change tightening behavior
• migrate onto string-contact surfaces

Use only product-approved lubrication where explicitly specified.

Storage

Store the guitar:

• Dry
• Away from condensation
• Away from aggressive chemicals
• In a clean case
• Without pressure on the FlowBar
• Without prolonged moisture in the spring cavity

After heavy playing, remove excessive sweat before closing the case.

After Changing Gauge or Tuning

Recheck:

• Bridge neutral position
• Spring arrangement
• Claw position
• Neck relief
• Action
• String radius
• Intonation
• Fine-tuner range
• Pickup clearance
• Full movement clearance

A gauge or tuning change is a new setup, not merely a new tuning operation.

Quick Setup Sequence

1. Install the intended strings.
2. Establish direct fine-tuner contact and useful range.
3. Release the locking nut.
4. Tune with the machine heads.
5. Stretch and stabilize the strings.
6. Balance the bridge through the spring claw.
7. Check neck relief.
8. Set bridge height and action.
9. Recheck neutral position.
10. Measure the actual string radius.
11. Set intonation with the strings detuned for each saddle movement.
12. Secure every saddle.
13. Tune the complete system.
14. Lock the nut.
15. Fine-tune.
16. Test dive and pull-up return.
17. Check all cavity clearances.
18. Recheck pickup height.
19. Perform a full playing test.
20. Inspect again after the first playing sessions.

Common Setup Mistakes

Avoid:

• Finalizing the setup with the wrong string gauge
• Locking the nut before the strings are stable
• Treating repeated tuning passes as a fault
• Correcting bridge angle through pivot height
• Correcting action through spring tension
• Setting action before checking neck relief
• Intonating before spring balance is stable
• Moving a loaded saddle under full string tension
• Setting intonation by visual saddle pattern
• Filing or reshaping FlowTrem2 saddles
• Installing conventional Floyd Rose saddle shims without KMS specification
• Adding a conventional fine-tuner spring plate without the dedicated KMS Support Shim and a revised block-height check
• Leaving fine tuners disengaged from the locking screws
• Overtightening titanium fasteners
• Forcing the pivot studs
• Ignoring block or screw contact inside the cavity
• Applying unapproved lubricant
• Using abrasive polish on coated or anodized components
• Assuming every tuning problem originates at the bridge

When Professional Service Is Recommended

Professional service is advisable when:

• Pivot inserts move in the guitar.
• Knife-edge damage is suspected.
• The bridge binds on the studs.
• The route restricts movement.
• The MONOLITH block contacts the cavity.
• Correct action cannot be reached.
• Neck relief is uncertain.
• Frets are uneven.
• Intonation cannot be reached within the available travel.
• The locking nut moves or is incorrectly positioned.
• Strings repeatedly slip despite correct installation.
• Threads or sockets are damaged.
• The spring claw is unstable.
• Electrical grounding is damaged.
• The guitar requires permanent modification.

Stop whenever adjustment requires unexplained force.

The FlowTrem2 Setup Principle

FlowTrem2 combines:

• Grade 5 titanium construction
• Precision knife-edge movement
• FlowTrem2 saddle geometry
• fine-tuner architecture without the conventional permanent Fine Tuner Tension Plate
• MONOLITH block architecture
• Extended intonation range
• OmniPort
• FlowBar

Final Validation

Before considering the setup complete, verify:

• Strings
• Saddles
• Locking screws
• Fine tuners
• Baseplate
• Knife edges
• Pivot studs
• Tremolo block
• Springs
• Spring claw
• Locking nut
• Guitar geometry

After the final adjustment, retune and repeat the complete dive/pull-up and return-to-pitch test. Any new drift, binding or contact should be diagnosed before the setup is considered complete.
