Shimming and Micro-Tilt™ Adjustment
Shimming is a procedure used to adjust the pitch, or angle of the neck in relation to the body and may be accomplished with either the use of
a shim or by performing a Micro-Tilt adjustment. The need to adjust the pitch may occur when the relative string height is high, but the action
adjustment is already as low as the string height adjustment will allow. A shim or a Micro-Tilt adjustment will tilt the neck back, relative to the plane
of the body, which allows an increased range of action adjustment.
The Micro-Tilt adjustment is a feature on some Fender® basses, that performs the same function as shimming, by tightening a hex screw in the
neck pocket of the body against a pressure plate installed in the bottom of the neck. The Micro-Tilt eliminates the need to remove the neck from the
body to perform the adjustment.
For those basses with the Micro-Tilt adjustment and a 3-bolt neck plate, first loosen the two neck mounting screws at the top, 1/2 turn. Next, loosen
the neck mounting screw nearest to the adjustment access hole on the neckplate by at least 4 full turns, (Figure L). Then, tighten the hex screw
through the hole in the neck plate with a 1/8" hex wrench approximately 1/4 turn, (Figure M). Retighten the neck screws when the adjustment is
complete.
