2. TRUSS ROD ADJUSTMENT
The adjustable truss rod in the neck of your Guitar has been shop adjusted
and should not require any change. If the neck should develop a dip or hollow
spot over time it can be removed by tightening the truss rod adjustment nut
that protrudes from the base of the headstock just above the nut.
A back bow or hog-back can be removed by loosening the nut. Great care
should be taken with truss rod adjustments where as little as 14 of a turn can
vastly alter the shape of a neck. A broken truss rod of course means a costly
replacement.
3. STRING ACTION
The string action refers to the height of the strings above the frets. If the
action is too low, the strings will buzz on the frets. If it is too high the guitar will
be difficult to play.
4. ACTION AT THE NUT
Setting the string action that is right for you starts at the string nut. The slots at
the string nut should already be close to perfection but you might want to
make some adjustment. Here’s how to do it!
Push the sixth string down between second and third fret. The space between
the top of the first fret and the bottom of the string should be about .006” or
just about the thickness of the paper that these instructions are written on. If
the gap is wider than .006” you should deepen the slot with a small needle file
until it is correct.
DO NOT FILE TOO DEEP!
If the slot is too deep you can fill
the slots with a mixture of white plastic sanding dust and super glue and then
re-shape the slot.
Repeat this same procedure for the other 5 strings. The action at the nut is
either right or wrong; it is not a matter of personal preference.
Now let’s adjust the height of the strings over the 12th fret. Minor adjustments
in the string action can be made by raising or lowering the individual saddles
on the tremolo bridge with the small hex key that has been provided with your
Guitar Kit. Following is a chart to assist you. This action adjustment is a
matter of personal preference. There should be a gradual increase in height
from the first to the sixth string.

Action can also be adjusted by changing the angle of the neck. This can be
done by inserting small shims between the neck and the body to increase or
decrease the neck angle.
