— If the string heights are correct, then con-
tinue to the next sub-section.
— If the string heights are incorrect at the
12th fret, this is an indication that the
groove the saddle sits in needs to be
either deepened or made shallower. This
condition is most likely a result of wood
movement due to humidity changes in
the environment. We recommend having
a qualified guitar technician raise or lower
the saddle before continuing.
— 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
condition is most likely a result of wood
movement due to humidity changes in
the environment. We recommend hav-
ing a qualified guitar technician raise or
lower the nut before continuing with string
height adjustment at the 12th fret.
