TRUSS ROD ADJUSTMENT

PICKUP HEIGHT ADJUSTMENT

The curvature of the neck should be slightly concave.
Clockwise rotation of the nut tightens the rod and corrects for
too much concave bow. Counterclockwise rotation of the nut
loosens the rod and corrects for too much convex bend. Make
any adjustments gradually. Allow five to ten minutes for setting,
and check the curvature after each 1/2 turn of the truss rod nut.

The height of the pickup (i.e. distance from the strings) affects
gain — the higher the pickup, the louder the sound, and vice
versa. If the pickup is set too high, sustain and playability will
suffer because of the magnetic pull on the strings. Adjust over-
all height using the screws located at either side of the pickup.
If the pickup has individually adjustable polepieces (most
humbuckers do), these can then be adjusted to achieve the
best overall balance. The polepieces should normally be about
2 or 3 millimeters from the strings.

NOTE: Unless you have experience with truss rods, we sug-

gest that you entrust this adjustment to your dealer.
