Double-Locking Tremolo
The Floyd Rose double-locking tremolo was popularized in the early 80’s and has remained a popular
system ever since. This system locks the strings both at the string saddle and the nut (Figure 16). By
locking the string at both locations, there is minimal if any string slippage and almost no friction except
at the point of the knife-edge/pivot studs. This results in a guitar that stays in tune extremely well, and
allows the pitch of the strings to be manipulated via the tremolo arm or “whammy bar”.
On ESP guitars, this bridge is almost always installed with a recess route in the body, allowing the bridge to rest
lower than a traditional bridge. This also allows room for both pulling up in pitch and pushing down in pitch. This
system is also referred to as a floating bridge since it does not rest against the body of the instrument.
An important thing to keep in mind about this system is that since this bridge uses springs in the back
of the body to balance against the tension of the strings, any change in tuning or string gauge will
drastically affect the performance and require adjustments to be made. The tremolo arm is inserted into a
fitting on the treble side of the bridge and then the threaded collar on the arm can be tightened by hand
to the desired level of tightness.
Note: There are two versions of Floyd Rose licensed bridges found on ESP instruments and the main
difference is the location of the string lock-down screws in relation to the string saddles. This alternate
version is referred to as a Low-Profile design.
CHANGING STRINGS (Floyd Rose Double-Locking Tremolo)
Note: We recommend that you only change one string at a time until you are familiar with this process.
Removing all the strings at once will cause the tremolo to pull back into the recess route and will make it
harder to change the strings and retune your guitar. Changing string gauges will also drastically change
the settings and make the bridge lift up high off the body or sink back into the recess route.
Refer to Figure 16:
1. Loosen pressure pad lock-down screws on locking nut using a 3mm allen wrench. Loosen string using
tuning key and remove string completely using string cutter.
2.
Loosen string lock-down screw on bridge using a 3mm allen wrench. Remove string from saddle.
3. Cut off ball-end of new string above the string winding and insert string in front of the string-lock block.
4. Tighten string lock-down screw so that it is snug. Note: Do not over tighten this screw as it can strip
the threading inside the saddle.
5. Feed string through locking nut, under pressure pad, under string retainer and through tuning key
post, wind a couple of turns down the tuning key post and tune to pitch. Note: There is no need to use
special winding as described in the stringing & tuning section since your string will be locked down at
the locking nut.
6. Repeat steps 1 - 5 for each string.
7. After replacing the desired string(s), tune all strings to pitch, stretch strings, and retune. You will have
to re-tune your guitar a few times until the tremolo has settled and the guitar remains in tune. Once
your guitar is holding tune, tighten all three pressure pad screws. Note: Make sure the orientation of
the pressure pads match the drawing in Figure 16. If the pressure pads are not oriented properly in the
locking nut, the strings will not lock down properly and you may experience tuning problems.
Fine Tuning
Once your strings are locked at the nut, you can fine-tune your guitar using the fine tuners located on the
tremolo behind the string saddles.
Note: If fine tuners run out of adjustment, loosen the pressure pad lock-down screws at the locking nut,
adjust your fine tuners into the middle of their adjustment and retune using your tuning machines on the
headstock. Once the tuning is stable, lock down the strings at the locking nut and you may use the fine
tuners again.
Adjusting String Height
There are 2 screws also referred to as pivot studs which raise or lower the Floyd Rose bridge (see diagram).
These screws are located at the front of the bridge – one on the bass side and the other on the treble
side. Turning the screws clockwise will lower that side of the bridge while turning counter-clockwise will
raise that side of the bridge. Note: The base-plate of the bridge should be parallel to the top of the body.
If the bridge-plate is angled too high or too low, you need to first adjust the spring tension located in the
back cavity of the guitar before you adjust the bridge height using the pivot studs.
Adjusting Intonation
Adjusting the intonation on a Floyd Rose bridge requires a few more steps and a little patience in
comparison to most bridges. After you have determined which way the string saddle needs to be moved,
loosen the pressure pad screw on the locking nut then loosen the string you will be adjusting. Next,
loosen the saddle lock-down screw and move the saddle forward or backward. Tighten the saddle lock-
down screw, tune string to pitch and check intonation. Continue repeating this process until the intonation
is set. Once you are done, lock down the string at the nut by tightening the pressure pad screws.
Adjusting The “Float” Level (Spring Tension)
The tremolo springs are located in the cavity on the back of the guitar.
You must remove the plastic backplate to access the tremolo springs
and adjustment claw. The tremolo springs are used to counter-act the
tension of the strings and adjust the angle of the bridge on
the top of the guitar. When your guitar is tuned
to pitch, the tremolo’s base plate should rest
parallel to the top of the guitar body. If you
notice your bridge angled upward or backward
into the recess route, then you need to adjust
the tremolo springs to bring the bridge back to the
correct angle. If your tremolo is angled away from
the body, then the springs need to be tightened. If the
tremolo is angled into the recess route, the springs need
to be loosened. Loosen or tighten each screw about 1⁄4 turn
if needed, then retune your instrument (Figure 17). You may
need to repeat this process a few times until finally your bridge
remains in tune and rests parallel to the top of the body.
There are different combinations of spring placement that can
be used based on your string gauge and tuning preference.
