Installation and Connections
WARNING: The solder pad terminals and the adjacent components on the
Powerchip circuit board are quite fragile and can be easily overheated. Use
only a low wattage soldering iron (30 watts max) to make your wire connec-
tions. To best utilize the space inside the guitar, solder the wires to the cir-
cuit board so that they exit toward the volume pot terminals.
1. Strip 3/32” (2.4 mm) and tin the wire ends of the pickups
2. Solder the Piezo pickup wire to the circuit board
The pads are located on the side of the board opposite the volume pot. The
Piezo hot wire goes to the pad on the right edge of the board, directly under
and to the right of the little white trimmer pot. Solder the Piezo ground wire
(which should be left with the braid intact), to the pad labeled “G” on the
right edge of the board, directly under the Piezo hot wire.
