instructions carefully. If you have any questions or problems, contact our PRODUCT INFORMATION LINE at 978-988-9665. The Fishman AGP-2 and ABGP preamps are specifically designed for use with piezoelectric pickups. Since piezoelectric pickups require specific elec- trical environments, the AGP-2 / ABGP feature discrete input stages that maximize the full potential of the pickup. Both units provide active gain con- trol and fully buffered shelving style active boost and cut for BASS and TREBLE. The center frequencies of these controls have been selected for their relationship with acoust ...

3 2. TEMPLATE A drilling template is provided for drilling the control shaft holes. Cut out the template outline. Check that it fits between the upper and lower linings when held inside the guitar at the chosen location. Tape the template at the location on the outside of the guitar. With a sharp scribe, pierce the tem- plate at the marks. Remove the template. This should provide you with two drilling centers marked on the side of the guitar. These centers will be 1.250 inch (31.8mm) apart. At each center, drill a .375 inch (9.5mm) hole through the side of the guitar. We recommend using a sharp 3/8 inch spur bit for this ...

4 holes from the inside of the guitar. Next, measure the length of the threaded bushing that protrudes out from the side of the instrument. From this mea- surement, subtract the thickness of the outside hardware (hex nut and finish washer). 5. WIRING THE TRANSDUCER Remove the cover from the AGP-2 Preamp. Locate the terminal block with two sections to be used to connect the transducer leads (see Figure 2). Thread the transducer wire through the rubber grommet where the wire harness enters the preamp. Strip and tin the signal and ground wires from the transducer and connect them to the terminal block as shown in Figure 2. Check for shorts. R ...

tery 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 ...

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 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 refer- ence position. 12. READY FOR USE The p ...
