Here’s a bass fuzz designed by Charlie Barth from Moosapotamus.net based on the fuzz section of the classic Acoustic 360 bass preamp. It uses a mix of silicon and germanium transistors. I’ve made the layout to reflect the combination of transistors specified in Charlie’s schematic, but socket and experiment. This layout should fit in a 1590B, but if you want to use a larger enclosure, there’s a PCB of this effect for sale here with board-mounted pots.
