Prepare the Endpin Hole for the Jack
There are two ways to widen the endpin hole to accept the preamp.
Slow and Safe
If you have the time, this is the preferred method. Remove the endpin and
widen the hole to size with a 15/32" (11.9 mm) reamer (available in the US
& Canada through Stewart MacDonald, 800-848-2273 part #4323).

Quick & Clean
The objective here is to quickly drill out the endpin jack hole, with the endpin
or other suitable plug in place. You may remove a loose endpin and refasten
it in the endblock with cyanoacrylate glue before starting the procedure.
Note: We do not recommend this method for instruments with brittle
ornamental veneers (ex: abalone) around the endblock.
1. Apply masking tape around the endblock area to protect the instrument.
2. Locate an X-Acto
®
saw blade 1/16" (1.6mm) 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" (3.2mm) pilot hole through the endpin.
5. Line up a 15/32" (11.9mm) 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.
6. To avoid damage to the instrument, let the drill come to a complete stop
before removing it from the hole.
Solder the Wire Connections
1. Unscrew the shielding cap to access the preamp circuit board.
2. Strip 1/4" off the outside jacket of the pickup wire. Tin both the inner con-
ductor and the ground wire.
3. Thread the pickup wire through the shielding cap.
4. Thread the pickup wire through the center strain relief hole, then solder the
signal wire from the pickup (hot wire) to the pad marked "IN" on the preamp
circuit board. Solder the ground wire from the pickup (shield) to the adjacent
pad marked "G" on the preamp circuit board. (See Fig 1) Do not over heat
the solder pads! Doing so may lift the pads from the circuit board.
5. Fasten the shielding cap to the jack. Be careful not to allow the shielding cap
to come in contact with the end of the circuit board.
6. Lock the shielding cap to the first large hex nut.

Fasten the Jack in the Endpin Hole
Follow this sequence when installing the endpin jack:
1 - Preamp / Shielding Cap
2 - 1st Large Hex nut
2
3 4 5
3 - 2nd Large Hex Nut
4 - Large Dress Washer
5 - Star Washer
6 - Guitar End Block
7 - Small Dress Washer
1
8 - Small Dress Nut
9 - Strap Button
The jack should protrude at least 5/16" (7.9 mm) and no more than 11/32"
(8.7mm) outside the guitar's body for proper fit.
Fit the small dress washer and nut over the end of the jack, then insert a 3/32"
Allen wrench through the small hole on the end of the jack. Tighten the nut
with a 1/2" open-end wrench while holding the jack in place with the Allen
wrench. Thread and hand tighten the strap button.
Note: With the strap button in place, the end of
the jack should protrude slightly, so that when a
plug is inserted, it will snap securely in place.

Attach the Battery Clip
We recommend that you attach the battery clip to a small piece of hardwood
R
approximately 1 1/2" x 1 1/2" x 1/2" (4cm x 4cm x 1.1cm) thick. Mark the screw
hole locations on the block using the battery holder as a template. Drill the screw
Zener
holes using the 5/64" (2mm) drill. Attach the battery holder using the two supplied
Diode
1/4" screws. Attach this assembly to the inside front block (neck block) using either
wood glue or a gap filling cyanoacrylate such as Loctite
Important!
Although the supplied battery holder should provide adequate
capacity to grip the battery at all times, we strongly recommend that you remove
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 damage incurred to instruments from a loose battery.

A set of adhesive backed clips has been provided to secure the pickup cable
and battery leads inside the guitar once the endpin jack has been installed.
Remove the plastic film from the back of each clip to expose the adhesive.
Secure the cable/clips to the kerfed lining of the guitar.

Solution
Push the saddle down over the weak strings.
Check bottom of saddle for flatness and squareness.
Remove debris from the saddle slot.
Make sure that the saddle has a sliding fit in the slot.
Do not use bone, ivory or other organic materials
for the saddle material. We recommend the
Fishman Cleartone™ high-performance saddle.
Follow the 50/50 rule.
Sculpt the bottom of the saddle to compensate for depth
differences in the saddle slot or re-rout the saddle slot.
The wire hole must be .094" diameter.
The saddle slot must be .125" wide for Wide Format and
.094" for Narrow Format. Rout the slot to the correct width.
Check saddle for sliding fit in the slot.
Examine the pickup. Replace pickup if the material is torn.
Fasten the Shielding Cap to the jack.
Observe the 50/50 rule. Ramp the string slots if necessary.
Align or widen pickup wire hole.
Widen or lengthen pickup saddle slot
to accommodate the pickup.
