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

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.
Tuning Machine Tension Adjustment
(Steel String Model)
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.
