Double-Sided Adhesive Tape Attachment
2. Determine how many spacers and/or cushions
will be needed to attain proper height for the
pickup.
With the backing still in place, stack spacers
A (1mm thick), B (0.3mm thick), and the
cushion underneath both ends of pickup (with
the pickup underneath the strings) until proper
clearance between the strings and magnetic
yokes is achieved (
 pg. 7). Do not remove
the backing from the cushions or spacers
when initially setting up the pickup height.
Initially use spacers A (1mm thick) and the
cushion to gain the approximate height
necessary, then use spacers B (0.3mm thick)
to fine-tune the height of the pickup.
* Before you adjust the pickup height, make sure
that the bass guitar is properly tuned.
* Please note that the cushion/spacer backing
adds about 0.1 millimeter to their thickness, so
take this added thickness into account when
using a number of spacers.
* If the body surface is not flat, use the double-
sided adhesive tape or cushion to attach the
pickup to the bass guitar body so that the
pickup properly adheres to the body.
* If you need to compensate for differences in
height between the low and high strings, cut
the double-sided adhesive tape and cushion
into one-quarter or one-third widths and adjust
the height.
3. Once the number of pieces has been deter-
mined, apply the cushions (with double-sided
adhesive) or double-sided adhesive tape to the
bottom of the pickup, then apply one spacer
and check the clearance with the clearance
gauge while the highest note on the neck is
fretted (
 pg. 7). Add spacers one by one,
continually checking the clearance, until the
proper height is attained. Do not remove the
backing from the tape that is used to attach to
the pickup to the bass guitar body until you
are sure that proper height is achieved.
4. Once the proper height is achieved, remove
the backing from the tape used to attach the
pickup to the body. Keeping the exposed tape
from coming into contact with the body, slide
the pickup under the strings. From the high
string side of the bass guitar, slide a minus
driver or similar tool under the strings, to help
support the pickup from the opposite side.
Once the pickup is slid into position, attach
the pickup/spacer assembly to the body.
* Make sure that the bass body is free from dust
and oil which might prevent the adhesive from
sticking to the body.
* Holding both ends of the pickup, apply light
pressure to attach the pickup to the body.
5. Once the pickup is attached and the height
has been adjusted, adjust the input gain levels
on the Guitar MIDI Converter (Refer to pg.
14. Also, the Guitar MIDI Converter manual).
* To remove the divided pickup from the body
without causing damage to the bass body, leave
the spacer attached to the body in place and
gently pry off the second layer spacer.
