(8.7mm) outside the guitar's body for proper fit.

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.

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.

Additional Volume & Tone Controls

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 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.

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.

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.

	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.	Remove debris from the saddle slot.
	Improper saddle fit (too tight or loose).	Make sure that the saddle has a sliding fit in the slot.

Fasten the Jack in the Endpin Hole

Follow this sequence when installing the endpin jack:

1	- Preamp / Shielding Cap
2	- 1st Large Hex nut
3	- 2nd Large Hex Nut	2 3 4 5	6	7 8 9
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"

			Uneven or belly up saddle slot.	Sculpt the bottom of the saddle to compensate for depth
				differences in the saddle slot or re-rout the saddle slot.
			Wire hole too tight.	The wire hole must be .094" diameter.
			Pickup binding in saddle slot.	The saddle slot must be .125" wide for Wide Format and
				.094” for Narrow Format. Rout the slot to the correct width.
			Improper saddle fit (too tight, resulting in poor s/n ratio).	Check saddle for sliding fit in the slot.
Hum			Torn pickup shield.	Examine the pickup. Replace pickup if the material is torn.
			Unshielded jack.	Fasten the Shielding Cap to the jack.
Thin or weak signal
			Weak downbearing pressure due to low string break angle.	Observe the 50/50 rule. Ramp the string slots if necessary.
Pickup			Pickup binding in wire hole	Align or widen pickup wire hole.
			(wire hole too small or misaligned).

or dead			Pickup binding in saddle slot.	Widen or lengthen pickup saddle slot
				to accommodate the pickup.
