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 conduc-
tor and the ground wire.
3. Thread the pickup wire through the shielding cap.
4. Thread the pickup wire through the largest of the three strain relief holes,
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.

Optional Stereo Wiring
The Fishman Switchjack™ switching endpin jack is integrated into the
Powerjack™. A variety of stereo wiring options are available for micro-
phone or pickup:
Two Pickups
Pickup & Microphone
(use with Fishman Blender System)
Additional Volume & Tone Controls
Fasten the Powerjack™
in the Endpin Jack Hole
Follow this sequence when installing the endpin jack:
1 - Preamp / Shielding Cap
2 - 1st Large Hex nut
3 - 2nd Large Hex Nut
4 - Large Dress Washer
5 - Star Washer
6 - Guitar End Block
7 - Small Dress Washer
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 a
3/32” (2 mm) 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
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
holes using the 5/64" (2mm) drill. Attach the battery holder using the two supplied
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 Black Max™.
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.

Symptom

Solution
AG-125 / AG-094 Troubleshooting
Saddle is not completely seated.
Push the saddle down over the weak strings.
Bottom of saddle is uneven or out of square with its sides.
Check bottom of saddle for flatness and squareness.
Debris in the saddle slot.
Improper saddle fit (too tight or loose).
Saddle material.
Not enough downbearing pressure on saddle.
Uneven or belly up saddle slot.
Wire hole too tight.
Pickup binding in saddle slot.
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.
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 the AG-125 and .094”
for the AG-094. Rout the slot to the correct width.
Thin or weak signal
Weak downbearing pressure due to low string break angle.
Observe the 50/50 rule. Ramp the string slots if necessary.
Hum
Improper saddle fit (too tight, resulting in poor s/n ratio).
Check saddle for sliding fit in the slot.
Torn pickup shield.
Examine the pickup. Replace pickup if the material is torn.
Unshielded jack.
Fasten the Shielding Cap to the jack.
Pickup
intermittent
or dead
Pickup binding in wire hole
(wire hole too small or misaligned.)
Align or widen pickup wire hole.
Pickup binding in saddle slot.
Widen or lengthen pickup saddle slot
to accommodate the pickup.
