To check the string heights of the 1st and 6th
strings at the 12th fret:
1. Measure the string heights at the 12th fret
(Figure 34).

— If the string heights are correct, then con-
tinue to the next sub-section.
— If the string heights are incorrect at the
12th fret, then continue to the next step.
2. With the supplied 1.5mm Allen wrench,
adjust the string saddle setscrews until the
string heights are correct.
• Turn the screws clockwise to raise the
height of the string saddle; therefore,
increasing the string height.
• Turn the screws counterclockwise to
lower the height of the string saddle;
therefore, decreasing the string height.
3. Adjust the middle strings so they gradually
increase in height from the 1st string height
through the 6th string height.
— If the string heights are correct (Figure
33), then move to checking the string
heights at the 12th fret.
— If the string heights are incorrect at the 1st
fret, this is an indication that the groove
the string nut sits in needs to be either
deepened or made shallower. This condi-
tion is most likely a result of wood move-
ment due to humidity changes in the envi-
ronment. We recommend having a quali-
fied guitar technician raise or lower the
nut before continuing with string height
adjustment at the 12th fret.
