The ACOUSTIC MATRIX transducer is a multi-layer configuration of
continuous strips of sensing material that are fully EMI shielded.
This continuous strip design allows it to sense the motion of the
entire saddle rather than small sections of it (as is the case with
traditional ceramic based transducers); providing superb string balance.
NOTE: Always handle the pickup with care. Mishandling may result
in ground hum or intermittent signal. Fishman Transducers will not
be responsible for any damages that may occur due to misuse or
poor installation.

We recommend a saddle slot length of at least 2.875" (73mm).
The actual sensing area of the pickup is 2.670" long and can accommodate string spacings of up to 2.500" (63.5 mm). Poor string balance may result with string spacings greater than this.
DO NOT trim the end of the pickups length as ground hum will occur.
Custom pickup lengths are available from Fishman.
COMPENSATED SADDLES
We do not recommend compensating the saddle under the "B" string.
Doing so may twist the saddle and cause uneven pickup response.
PREPARE THE SADDLE SLOT
1. Rout a .125" (3.2 mm) wide saddle slot
for the Acoustic Matrix Wide Format
pickup.
OR
Rout a .09375" (2.3 mm) wide
slot for the Acoustic Matrix
Narrow Format pickup.
2. Be certain that the bottom of the slot is FLAT.
Deepen an existing slot only enough to obtain a clean, flat surface.
LOCATE THE WIRE HOLE
1. Locate the center of the wire hole no less than .100" (2.5 mm) from
the closest string.
2. Mark the location where the wire will enter the saddle slot. Center
the mark between the walls (width) of the slot.
3. Drill a .09375" hole.
4. Clear wood chips and foreign materials from the saddle slot.
5. Carefully insert (do not bend) the pickup.
MECHANICAL FACTORS AFFECTING
PICKUP PERFORMANCE
BREAK ANGLE
There must be an adequate
amount of downbearing pressure on the pickup in order
for it to perform optimally.
The pickup will "see" an acceptable amount of downbearing pressure
when there is a 20° (minimum) break angle across the saddle.
A pickup in a Guitar with less than a 20° break angle will often have
string balance problems as well as poor tone. For such instruments,
an adequate break angle can be realized by "ramping" the string slots
or (in extreme cases) raising the saddle height and resetting the neck
angle.
THE 50/50 RULE
PREPARE THE SADDLE
For adequate coupling between string, saddle and pickup, we recommend that the saddle slot depth (with pickup installed) should equal no
more than 50% of the total height of the saddle.
We recommend synthetic materials such as Micarta or Corian as
excellent saddle materials for the Acoustic Matrix. Organic materials
such as bone or ivory are not as consistent and may result in poor
string balance.
ADJUSTING FOR TOO DEEP A SADDLE SLOT
1. Prepare a .125" wide saddle (.09375" for Narrow Format) The bottom of the saddle must be FLAT.
WARNING
INSTALLATION BY A QUALIFIED PROFESSIONAL REPAIRMAN IS
STRONGLY RECOMMENDED. FISHMAN TRANSDUCERS WILL
NOT BE RESPONSIBLE FOR ANY DAMAGES THAT MAY RESULT
FROM IMPROPER INSTALLATION.
EXCEPTION: Pickups in guitars with a very steep string break angle
(25° or more), will generally perform well, even if the saddle slot depth
measures more than 50% of the total saddle height.
If the slot (with pickup installed) measures more than 50% of the total
saddle height, the pickup performance will often suffer. To correct for
too deep a slot, place a wood shim under the pickup. Determine the
proper thickness of the shim by subtracting 1/2 of the total saddle
height from the slot depth (with pickup installed). Then, remove an
amount of material equal to the thickness of the shim from the bottom
of the saddle.
2. Remove only enough material from the width of the saddle to provide a sliding fit in the slot. To test the fit, the saddle should slide
easily in the slot, but should not fall out when overturned. To maintain your current action, the new saddle must be .053" shorter in
height (.043" for Narrow Format pickups) than your current saddle.
PART I - PREPARATION Cont’d.
PREAMP CUT-OUT
For guitars with non-laminated sides, we strongly recommend gluing a
thin plywood patch inside the guitar before cutting out the cavity. This
will prevent cracking and splintering of the cut-out area during cutting,
and provide adequate structural support for the preamp.
1. Choose the preamp location on the side of the instrument.
Note that the bezel has the ability to conform to most curved surfaces on standard size guitars.
2. Tape the enclosed Cutout Template to the desired location.
Use the flex shaft tool (with 1/2" blade) or the router (with 1/4" cutter) to make the cut-out.
3. Drill the screw mounting holes using the 1/8" drill.

a complete stop before removing it from the hole.
SOLDER THE WIRE CONNECTIONS
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.

The objective of this method is to drill a hole in the endblock, with the
endpin in place. You may remove a loose endpin and refasten it in the
endblock with cyanoacrylate glue before starting this procedure.
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

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 relation to the instrument. Use
steady (but not heavy) pressure, especially as the drill exits inside
the guitar.
IMPORTANT: To avoid damage to the instrument, let the drill come to
The jack should protrude at least 5/16" and no more than 11/32" outside of the body for proper fit. After fitting 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.
MOUNT THE PREAMP
OPERATION
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 guitar.
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 larger 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.
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
relationship 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.
