Adjusting the Bridge Height: Step-by Step Instructions
Note: The strings do not need to be loosened to make bridge height adjustments.
To access the action height adjustment screws, remove the four cover plate screws
(Fig 1)
, then remove the plate.
Raising the Action
1) Using a 3/8 (10 mm) socket or nut driver, carefully loosen the
treble side anchor nut ½ turn counter-clockwise.
Note: Usually a ½ turn counter-clockwise is enough to allow the height adjustment
screw to then be raised. Do not remove the anchor nuts or the bridge will come off.
2) Using a 3/32 Allen wrench, turn the height adjustment screw
½ turn clockwise to raise the bridge. (The
locking nut will get tight again as you raise the height.)
3) Tune and check the string height.
4) Repeat the process until the desired action is achieved, then
follow the same steps for the bass side.
5) Tighten the anchor nuts. Do not over-tighten them or it could
break the bridge.
Lowering the Action
Note: The anchor nuts do not need to be loosened to lower the bridge height.
They will, however, need to be retightened as the action is lowered. Snug tension
is all that is required. Do not over-tighten the anchor nuts.
1) Using a 3/32 Allen wrench, loosen (lower) the center height
adjustment screw one full turn counter-clockwise. This will back the
center pivot point away from the bridge, allowing it to be lowered.
2) Using a 3/32 Allen wrench, loosen (lower) the treble side height
screw ½ turn counter-clockwise.
3) Using a 3/8 (10 mm) socket, retighten the anchor nut after
each lowering adjustment is made. Only snug pressure is needed.
4) After making treble and bass side height adjustments, raise the
back height adjustment screw until it just starts to lift the back
of the bridge.
