1.
Apply masking tape around the endblock area to protect the instrument.
2.
Locate an X-Acto saw blade 1/16" away from the body and saw off the endpin.
3.
Centerpunch a guide hole in the center of the trimmed endpin.
4.
Drill a 1/8" pilot hole through the endblock.
5.
Line up a 15/32" Spade bit in the pilot hole and begin drilling. Maintain a perpendicular plunge in rela-
tion to the instrument. Use steady (but not heavy) pressure, especially as the drill exits inside the gui-
tar.
IMPORTANT:
To avoid damage to the instrument, let the drill come to a complete stop before removing it
from the hole.

1.
Insert the pickup in the saddle slot then strip and tin
the wire ends.
2.
Solder the "hot" wire from the pickup (inner conductor)
to the pad marked "IN" on the preamp circuit board.
Solder the "ground" wire from the pickup (shield) to the
pad marked "GND" on the preamp circuit board.
3.
Strip and tin the wire ends of the preamp output cable.
Solder the red wire to TIP, the black wire to RING and the
ground wire to the SLEEVE of the 1/4" jack.

Follow this sequence when installing the endpin jack:
1 - Shielding Cap (optional)
2 - First Large Hex Nut
3 - Large Dress Washer
4 - Star Washer
5 - Guitar Endblock
6 - Small Dress Washer
7 - Small Dress Nut
8 - Strap Button
The jack should protrude at least 5/16" and no more than 11/32" outside of the body for proper fit. After fit-
ting the small dress washer and nut over the end of the jack, insert the 3/32" allen wrench through the cross
drilled hole on the end of the jack. Tighten the nut with the 1/2" open end wrench while holding the jack in
place with the allen wrench. Thread and hand tighten the the strap button.
NOTE:
With the strap button in place, the end of the jack should protrude
slightly to allow proper plug fit.

The hardware supplied will accommodate guitars with laminated sides that are between .100" and .175"
thick. If your guitar has sides less than .100" thick, the slider knobs will not fit in the bezel properly.
To make up the difference, use #4-40 washers to shim the preamp inside the instrument or contact Fishman
for longer standoffs.
1.
Fasten the 3/16" brass hex screws and the 1/4" hex standoffs to the preamp as shown. Note that the
mounting holes on the volume control side of the circuit board are slotted to allow for fitting the preamp
to the curved surface of the guitar side.
2.
Temporarily fit the preamp and bezel together on the guitar, with the standoffs finger tight. Fasten the
bezel with the #4-40 1/2" screws to check the standoff alignment. Align the standoffs if necessary.
Remove the preamp from the guitar. Tighten the aligned standoffs secure.
3.
Mount the backplate to the preamp with the 3/16" #4-40 screws. Install the battery and string up the gui-
tar.
4.
Plug the guitar into an amplifier and set all the slider's tone controls to their center positions. On the
back of the preamp, there is a recessed Sub-Bass control which is preset at the factory to full boost.
This can be used to roll-off the amount of “bottom end” which can cause feedback (especially in larg-
er dreadnought-style guitars). Turn the trim pot counter clockwise for less bass.
5.
Re-install the preamp into the guitar. Be sure that the low battery LED lines up with the corresponding
hole in the bezel.
6.
Attach the adhesive backed plastic wire guides to the sides or the kerfing of the instrument.
7.
Insert a 9 Volt Alkaline battery into the battery clip.
IMPORTANT:
Although the supplied battery holder should provide adequate capacity to grip the battery at
all times, we strongly recommend removal of the battery when shipping your instrument. FAILURE TO
REMOVE BATTERY COULD RESULT IN DAMAGE TO YOUR INSTRUMENT. Fishman will not be held
responsible for any such damage as a result of shipping or handling.

PERATION
The output jack of the Acoustic Matrix Professional System is also the
power switch for the battery. When a cable is first plugged into this jack,
the BATT/LOW LED will flash momentarily to indicate that the power is
on. When the battery power is low, this light will remain lit. Be sure to
unplug the output jack when not in use to avoid battery drain.
Adjust the volume of the preamp and your amplifier as desired. Using
your ears as a guide, set the PHASE switch for proper phase relation-
ship with the sound source (amps, monitors, etc.). This relationship is
most audible at louder volumes and will change from room to room and
with your position on stage.
