User manual FISHMAN TUNE-O-MATIC INSTALLATION GUIDE

[. . . ] This warranty does not cover any consequential damages or damage to the unit due to misuse, accident, or neglect. Fishman retains the right to make such determination on the basis of factory inspection. Products returned to Fishman for repair or replacement must be shipped in accordance with the Return Policy, as follows. [. . . ] A stereo "Y" cable or a standard stereo cable can then carry the two signals. From there, all mixing and blending functions will be performed offboard the instrument. A Fishman Powerblend pedal is especially suited for offboard blending/mixing with this passive setup. For a passive setup, you don't want to tie the PowerbridgeTM and magnetic pickup wires together at the guitar's mono output jack. If you connect the piezo and magnetic outputs, you will experience a loss of tone and a very bizarre and un-musical interaction between the PowerbridgeTM and magnetic pickups. Continued on other side Stereo Instrument Cable to Stereo Input Magnetic F ISHMAN P OWERBRIDGE TM P ICKUP I NSTALLATION G UIDE Wiring Instructions · Preliminary Notes To prevent 60 Hz hum, the entire PowerbridgeTM Pickup signal path should be fully shielded. The control cavity, jack cavity, and any non-conductive surface to which the controls are mounted (such as a plastic pickguard) must be shielded with adhesive-backed foil or conductive paint. For complete hum prevention, the included stereo jack should also be shielded. After you have soldered the wires to the jack, roll the foil into a tube so that the insulation is on the INSIDE and surround the stereo jack with the tube. Connect the foil side of the tube to ground by soldering it to the shielding of the PowerbridgeTM Pickup wire or to a jumper that is connected to any ground. If your instrument has active magnetic pickups (requiring an onboard battery), you will need a special 9 Pin Switching Jack (Fishman Part Number ACC-PBR-9PJ), available through your Fishman dealer. Continued from other side Magnetic and piezo pickups operate on different electrical platforms. Magnetics are "inductors" and piezos are "capacitive" devices. The solution is to electronically isolate or "buffer" the two signals with the Fishman PowerchipTM. Bridge Installation · Installation of the Fishman PowerbridgeTM should be performed only by a qualified repairman. Fishman Transducers will not be responsible for any damages that may result from improper installation. [. . . ] You will need: · 250 k (or 300 k for long shaft Les Paul®) audio taper pot · 330 k resistor · 820 pF capacitor · 1500 pF capacitor This network will attenuate the PowerbridgeTM so that it better matches levels between magnetic and piezo pickups. You can expect a 14 dB (nominal) decrease in PowerbridgeTM output with this circuit. NOTE: Optional 3-Way Selector Switch - If desired, a single pole, double throw (spdt) 3-way switch can also be added for piezo/magnetic pickup selection. Use a switch with an ON-OFF-ON orientation (no, this is not a misprint) NOTE: Active Onboard Blending A Fishman PowerchipTM (not included) must be installed if you wish to blend/mix piezo and magnetic signals onboard the instrument. Stereo Jack FILE HERE · Active Setup - Powerchip With our onboard Powerchip, you can mix and combine both the PowerbridgeTM and magnetic pickups (on the guitar) and plug right into a single channel guitar amplifier.
