Be sure to check and adjust the fit of the battery in the holder before installing the AGP-2 Preamp inside the instrument. 6a. OPTIONAL BATTERY HOLDER MOUNT Cut a block of 1/4” plywood approximately 1-1/2” x 2-1/2” (40mm x 65mm). Using two Number 4 pan-head sheet metal screws (1/4" length), attach the battery holder to the wooden block. The assembly can then be attached to the neck block with wood glue, double sided tape, or Velcro. 4 ONBOARD ACOUSTIC GUITAR PREAMP ONBOARD ACOUSTIC GUITAR PREAMP 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 or flying with 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. 7. MOUNT THE PREAMP Slip the wooden spacer block (prepared earlier) over the control bushings and mount the preamp. The outside hardware should include a smooth 3/8” dress washer and a 3/8” hex nut. Tighten the hex nut. 8. PREPARE THE ENDBLOCK The objective of this method is to drill a hole for the jack into the endblock, with the endpin in place. You may remove a loose endpin and refasten it with cyanoacrylate glue before starting this procedure. 1. Apply masking tape around the endblock area to protect the instrument. 2. Cut the endpin with an X-Acto saw blade 1/16" away from the body. 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 the 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 a complete stop before remov- ing it from the hole. 5 AGP-2 / ABGP AGP-2 / ABGP 9. WIRING THE OUTPUT JACK Solder the red wire to the tip (short terminal). Solder the black wire to the ring (longer terminal). Solder the shielding to the ground tab. After soldering, bend the strain relief tabs around the grey jacket. 10 - FASTEN THE JACK IN THE ENDPIN HOLE 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 guitar 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 small 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. 6 ONBOARD ACOUSTIC GUITAR PREAMP ONBOARD ACOUSTIC GUITAR PREAMP 11. KNOB ALIGNMENT The stacked knob set controls treble boost & cut (small knob) and bass boost & cut (large knob). Both knobs have a center-detent to indicate flat position. Place the bass (large outer ring) knob onto the stacked shaft so that the two inner protrusions slide into the corresponding slots on the outer shaft. Now place the smaller treble knob onto the inner shaft. The white position markers should align with each other in the center detent position. Now place the large volume knob onto the appropriate shaft; rotate the knob and remove to re-position the line if necessary for the desired sight reference position. 12. READY FOR USE The power is switched on only when a 1/4” mono guitar cable is plugged into the output jack. The AGP-2 features a “soft” turn on mode. This means that the unit powers up gradually over several seconds once the instrument is plugged in.
