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.

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.

Cool build with 3904's and all 34a's
ReplyDeleteVerified it too. I have got sound like Mark Knopfler played on "money for nothing". Used couple 1N4148 & germanium D9. I think can use any silicon diodes.
ReplyDeleteOne question, can I use LM386 M-1 (smaller version package, SOIC 8) for this project?
