Attaching the GK-3 to the Guitar
3. Adjust the height of the pickup.
Insert the supplied spacers under the
pickup until it is at the required height (do
not yet remove the protective paper backing
from the spacer’s double-sided tape).
There are three types of pickup spacers,
“A” (3 mm), “B” (1 mm) and “C” (0.25
mm); combine these as necessary to
achieve the proper pickup height.
* The pickup height should be adjusted so that the
distance between the pickup and the strings is about
1.0 mm (0.04”) when the highest frets on the first
and sixth strings are fingered. Check the height
using the supplied clearance gauge (1.0 mm), and
adjust the height as necessary (p. 11).
* If the first and sixth string heights differ greatly when
the highest fret is fingered, compensate by adding the
appropriate half-width or one-third width spacers
until the clearance for both strings is the same.
When using an arch-top guitar, put the
pickup cushions under the pickup spacers.

* Adjust the pickup cushion thickness as required, for
example by using two pickup cushions.
* The pickup spacers and the pickup cushions are
attached to the guitar with double–sided tape. When
affixing the tape, however, the tape’s thickness is
reduced by 0.1 mm (0.004”) when the backing of the
tape is removed. Therefore, when using several
pickup spacers, take this fact into account and set the
height slightly higher to compensate.
4. Remove the strings from your guitar.
5. Remove the backing from the tapes for
the pickup cushion, the pickup
spacers, and the pickup, and carefully
attach the pickup to the guitar.
* Although double-sided tape B is used for the pickup,
if the adhesive capability seems insufficient after
installation, use double-sided tape C instead.
* Using double-sided tape C strongly and securely
attaches the pickup. Note, however, that once the
pickup is attached with this tape, removal from the
guitar becomes difficult and may result in damage to
the guitar’s finish.
6. Restring and tune the guitar, then
carefully check the height of the
divided pickup once more.
Measure with the clearance gauge to
confirm that the clearances between the
pickup and the strings are approximately
1.0 mm (0.04”) when you press the first
and sixth strings at the highest fret, play
the strings and confirm that the strings do
not come into contact with the pickup.
7. Take the steps below if the height of
the divided pickup is not right.
1) Carefully examine the pickup in its
current state, and add a suitable
number of spacers if the pickup is
too low, or remove one or more
spacers if the pickup is too high.
2) Remove the strings from the guitar.
3) Remove the divided pickup from the guitar.
* Use care in handling the divided pickup; bending or
twisting it may cause breaking in the coil elements.
Carefully insert something thin and flat (like a table
knife) under the Pickup from the sixth string side,
then gently pry the pickup upwards.
