User manual FENDER DUO SONIC

[. . . ] We recommend the upper bout adjacent to the neck, or in the waist area. Avoid any location that may interfere with neck block, braces or linings. 2 ONBOARD ACOUSTIC GUITAR PREAMP WARNING INSTALLATION BY A QUALIFIED PROFESSIONAL REPAIRMAN IS STRONGLY RECOMMENDED. FISHMAN TRANSDUCERS WILL NOT BE RESPONSIBLE FOR ANY DAMAGES TO YOUR INSTRUMENT DUE TO IMPROPER INSTALLATION. 2. TEMPLATE A drilling template is provided for drilling the control shaft holes. [. . . ] 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 operation. FIG. SPACER BLOCK We strongly advise that a wooden spacer block (see Figure 1) be used to add strength to the mounting area of the guitar and to more evenly distribute the load of the preamp. We do not recommend using a hex nut and lock washer as the inside bearing surface to accommodate the thickness of the inside of your instrument because this could result in possible damage to the instrument itself 4. PREPARING THE SPACER Using the drilling template as a guide, make a rectangular wooden spacer that is 2. 00 inch x . 750 inch x T (50. 8mm x 19. 0mm x T). T is the measurement derived from the protruding bushing length minus the outside hardware thickness (Figure 1) To derive T, insert the control shafts through the 3 DUO SONIC / ABGP 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 measurement, subtract the thickness of the outside hardware (hex nut and finish washer). 5. 2 Remove the cover from the DUO SONIC Preamp. Locate the terminal block with two sections to be used to connect the transducer leads (see Figure 2). WIRING THE OUTPUT JACK Solder the red wire to the tip (short terminal). Solder the black wire to the ring (longer terminal). 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 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. [. . . ] This means that the unit powers up gradually over several seconds once the instrument is plugged in. SPECIFICATIONS SYSTEM GAIN 9 dB (input to output at 1 kHz) All tone controls flat.
