Setting String Height - Grizzly T10458 Instruction Manual

setting string height

the string height is the distance between the top
of the fret and the bottom of the string (figure
33). Correct string height is crucial for maximizing
the playability of the ukulele. Measurements are
taken at the 1st and 12th fret.

the string nut and saddle come oversized from
the factory. Sizing them requires measuring,
sanding, and re-measuring. Fix both the nut and
saddle until correct string heights are reached.
hand-sanding prevents removing too much
material.
to check the string heights at the 1st and 12th
frets:
1.
using a dime as a gauge (approximately
⁄ "), measure the string heights at the 1st fret
1
16
(see figure 34).

— if the string heights are at least the thick-
ness of a dime, then proceed to step 2.
— if the string heights are less than the thick-
ness of a dime at the 1st fret, this is an
indication that the height of the string nut
needs to be adjusted. proceed to step 3.
2. using a stack of three pennies (approximate-
⁄ "), measure the string heights at the 12th

fret (see figure 35).

— if the string heights are approximately the
thickness of three pennies, then continue
to step 5.
— if the string heights are less than the
height of three pennies at the 12th fret,
this is an indication that the height of the
saddle needs reduced. proceed to step
3.
3.
hand-sand the base of the string nut/saddle.
DO NOT remove too much material.
4.
test the string nut/saddle by repeating
steps 1–2.
5.
glue the string nut into place.
note: The nut and saddle may need to be
removed and resized if the neck of the uku-
lele warps due to moisture. Use only enough
glue to keep the string nut in place. The
saddle should not be glued.
