TRUSS ROD 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.

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

gest that you entrust this adjustment to your dealer.

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 hum-

buckers 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.
