This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Seppuku Space Fuzz

The Space Fuzz is a a loud, in your face fuzz/octave box from Japan builder Seppuku FX. It's partially based on the Tim Escobedo Rambler, with a couple other stages thrown in (including the Bazz Fuss). It has a pretty wide range of tones and can get a little splattery at the end of sustained notes. This layout is based on original PCB traced on FSB, but tidied up and changed to include power filtering and polarity protection, and will fit in a 1590B (originals are in 1590BBs). Originals use ceramic capacitors and that's reflected in the layout as well. Seems like just about any NPN silicon transistor will work, but the 2N2222 reportedly is the quietest. As always, socket and experiment.




Edit: John K over on FSB seems to have verified this layout using 2N5088s and a LM386N-3 with very little noise. If the effect does seem loud enough, try using a 1N4148 in place of the 1N34.
