[. . . ] Enclose a copy of the original Bill of Sale as evidence of the date of purchase, with the product in its original packaging and a protective carton or mailer. FISHMAN TRANSDUCERS' technicians will determine whether the item is covered by warranty or if it instead has been damaged by improper customer installation or other causes not related to defects in material or workmanship. [. . . ] 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. This may seem like a good idea, but it won't work. 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. The shielded cavities should then be grounded. For complete hum prevention, the included stereo jack should also be shielded. To do this, we've included a piece of shielding foil. 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. [. . . ] Remove the bezel and make a notch in the plastic (using a round jeweler's file) in the gap between the metal pickup housing and the screw hole closest to the high E string saddle. Then route the wire through the into the control cavity.
