TUNING MACHINE TENSION ADJUSTMENT

The tuning machines have spring-loaded mechanisms which automatically take

up wear, preventing backlash. However, it is possible to adjust the amount of

pressure required to turn the machines. Each machine has a tension adjustment

screw, as illustrated.

•

Clockwise screw rotation

tightens the machine. The

tuning machines should be

adjusted to the extent that they

are firm, but can turn smoothly.

This adjustment is normally

unnecessary, and excessive

tightening can lead to premature

tuning machine wear.

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 suggest that you

entrust this adjustment to your dealer.
