Attaching the Divided Pickup
Use the following steps if you need to read-
just the pickup height.
1. Determine the number of spacers you need
to add or remove.
2. Remove only the pickup from the body.
Without applying any excessive force to
the pickup, carefully pry the pickup from
the spacers by sliding a thin, flat object
under the low string end of the pickup,
and gently lifting the pickup away from
the spacer.
* Bending or twisting the pickup may cause
the coil inside the pickup to snap, resulting
in a damaged pickup. Use caution.
3. Carefully remove the double-sided tape
from the underside of the pickup.
4. Readjust the height as required. If spacers
must be added, remove the double-sided
tape from the existing spacer. If spacers
must be removed, be sure to remove both
the spacer and its double-sided tape.
5. Finally, attach fresh double-sided tape or a
cushion to the bottom of the pickup,
remove the backing, carefully attach the
pickup to the uppermost spacer.
6. Re-tune the bass and check the clearance
with the supplied clearance gauge.
7. If proper clearance is achieved, adjust the
input gain levels on the Guitar MIDI
Converter (Refer to pg. 14. Also, the
Guitar MIDI Converter manual).

Screw and Spring Attachment
It will be necessary to drill holes in the bass
guitar body to attach the pickup with screws
and springs.
1. Place the pickup in the position in which it
will be attached, then carefully mark the
centers of the two screw holes at either end of
the pickup on the bass guitar body.
2. Drill the screw holes. Carefully drill a 2mm
(0.08", approx.) diameter hole at both marked
locations. Make sure that the holes are drilled
vertically.
3. Insert the springs into the underside of the
pickup, insert the tapping screws (3x25)
through the screw holes and springs, and
screw the screws in the holes in the body.
4. With the bass properly tuned, adjust the
pickup height by loosening or tightening the
pickup screws. Adjust the clearance while the
highest note on each string is fretted. Pickup
clearance can be checked using the supplied
clearance gauge (
5. If proper clearance is achieved, adjust the
input gain levels on the Guitar MIDI Con-
verter (Refer to pg. 14. Also, the Guitar MIDI
Converter manual).
pg. 7).
