If you plan to install a Gate Booster, build the PCB now. The Fuzzbass Gate Booster is silkscreened
with reference designators for parts (ex: R1). The parts list below assumes you are performing
the standard install, and does not include optional parts for LED gate indication (R17: 1k, and Q3:
2N3904).
Ferrites may be replaced with wire jumpers. 10u electrolytic capacitors may be replaced with 1U
50V types. The DIP socket is optional. The point of headers and wire housings is to allow
disconnect for servicing. If you are using a header and wire housing on the main board for the
power connection, you can directly solder these wires to the power header location on the
Booster (you only need one disconnect).
