PRS Tremolo

trem Back in 1984, Paul Reed Smith was granted a patent on his tremolo system. The design elements are simple and resemble the traditional fulcrum tremolo but with some important differences.

1. In the front of a PRS bridge, the six leading edge screw holes are counter-sunk from underneath, providing six brass knife-edge fulcrums. These rest against the six notched brass body mounting screws. This knife-edge set-up ensures that the bridge will return to pitch after use.

2. The pocket in the tremolo bridge keeps the six individually adjustable saddles from moving sideways, thereby eliminating another traditional cause of tuning instability.

3. The tremolo block is drilled out so the ball ends rest right up under the bridge base plate. This leaves less string behind the bridge saddle so there is less chance of detuning, via proper string stretching.

4. There are no rough edges.

5. All adjustment screws are inset and made of brass.

6. The unthreaded tremolo arm fits into a hard plastic sleeve staying where you put it, via a small set screw on the side of the bridge that faces the tail end of the guitar (where the intonation adjustment screws are located) therefore it will not wobble or break off in the block.

Tuning and Setup Hints
If the guitar is returning sharp after using the tremolo arm, put a little lightweight machine oil under the head of each screw (do not loosen the screws). This will effectively oil the knife-edge of the tremolo.

The correct adjustment of the six brass screws, which act as a pivot and anchor the tremolo system, is level with each other so the bridge floats 1/16" off the body. These 6 screws are factory adjusted and you really should not have to adjust them at all. If it becomes necessary to adjust the 6 notched screws, make sure the guitar is detuned or you will ruin the knife-edge. Adjust the screws incrementally so the notches under the screw heads are fitted with the corresponding hole in the bridge. These holes serve as the knife-edge on which the tremolo unit rocks. Again, this is a very tricky adjustment and could ruin the knife-edge if done improperly.

The Bridge saddles should be low in the range of adjustment to keep the action low and leverage of the bridge in good working order. They should be adjusted so that the height of the string at the top of the 12th fret to the bottom of the string is 2/32".

If the tremolo bridge is not floating 1/16" off the body, remove the tremolo back plate. Adjust the claw screws about 1/4 turn at a time until the bridge floats perpendicular to and about 1/16th off the body. Tune to pitch and check, re-adjust until the bridge sits properly.
The intonation may be adjusted by moving the 6 phillips head screws facing the tail end of the guitar in and out with a phillips head screwdriver. Match the octave (fretted) note of all six strings with their corresponding 12th fret open harmonics by shortening or lengthening the strings with the adjusting screws.

Remember to tune and retune until the process is complete.

PRS Stoptail

Stoptail Designed to take full advantage of the resonant properties of our guitars, the PRS Stoptail Bridge provides direct transmission of string vibration to the guitar body and makes set-up a breeze. First used in 1991 on the PRS Dragon I guitar it now appears on almost half of all PRS guitars sold. This bridge features slots that recess the strings comfortably as they pass over the top, in a gentle curve. Although it is pre-compensated for modern string gauges, fine-tuning is possible by adjusting the set screws at each end of the bridge.

Tuning and Set-up Hints

Action height is adjustable by raising or lowering the studs that the bridge sits on. To adjust the mounting studs, first detune the instrument to relieve all possible string tension on the bridge. Next, using a Quarter, perform the necessary height adjustments to the bridge. Then, retune the guitar. Bear in mind that the brass studs are a soft metal that could be prone to marring if adjustments are made too forcefully.

Intonation can be adjusted using the two allen set screws facing the tail end of the guitar. A strobe tuner or other electronic tuning device should be used. Match the octave (fretted) note of the first and sixth strings with their corresponding 12th fret open harmonics by shortening or lengthening the strings with the adjusting screws using the allen wrench provided. Start with the treble side and then go to the bass side, return to the treble side for one last check. The other four strings are present and will intonate correctly provided a conventionally gauged string set with a plain third (G) string is used. Use of a wound third string is not recommended with this bridge.


When setting the action at the 12th fret the string height should be 2/32" on the treble side to 5/64" on the bass side.

Remember to tune and retune until the process is complete.

If you are unfamiliar with making these adjustments, we recommend that the guitar be taken to a qualified repair center.



Adjustable Stoptail

Adjustable Stoptail For ease of intonation of non-standard or extra heavy string gauges, a special order version of the PRS Stoptail with individually adjustable saddles is available. The adjustable PRS Stoptail is available in nickel or gold plate. All PRS parts and accessories are available for special order; please contact our accessories department for ordering information.

The Hollowbody and Archtop with the piezo option feature a special version of the adjustable PRS Stoptail fitted with piezo inserts. This bridge can be adjusted in the same fashion as our adjustable Stoptail.

Tuning and Setup Hints

Action height is adjustable by raising or lowering the studs the bridge sits on. To adjust the mounting bolts, first detune the instrument to relieve the tension on the bridge. Then using a Quarter, make the necessary adjustments and retune.

The intonation may be adjusted by moving the phillips head screws on the inside edge of the bridge (facing the treble pickup) in and out with a phillips head screwdriver. Match the octave (fretted) note of all six strings with their corresponding 12th fret open harmonics by shortening or lengthening the strings with the adjusting screws. Additional minor adjustments to the intonation may also be made by moving the set screws facing the tail end of the guitar in and out with the allen wrench provided.


When setting the action at the 12th fret the string height should be 2/32" on the treble side to 5/64" on the bass side.

Remember to tune and retune until the process is complete.

PRS Electric Bass Bridge

bass bridgeThe Electric Bass features a massive machined PRS designed bridge with heavy-duty saddles. The saddles are adjustable for string height and intonation and are prevented from sideways movement by the base plate sidewalls.

The intonation can be adjusted by moving the four phillips head screws facing the tail end of the bass guitar. Match the octave (fretted) note of all four strings with their corresponding 12th fret open harmonics by shortening or lengthening the strings with the adjusting screws.


When setting the action at the 12th fret the string height should be 2/32" on the treble side to 5/64" on the bass side.
