A simple and nasty octave up fuzz based on Tim Escobedos Push Me Push You fuzz. But here, the input transistor is replaced with a LM386 audio amplifier for more gain that pushes the transistors harder. Also, there is also a simple treble cut tone control added.
This build works! The only issue I'm having is that the output of the circuit is a little on the quiet side. The volume is way below the clean bypassed signal.
ReplyDeleteHowever, it is a nasty, dirty sounding octave up fuzz. Just a little quiet.
I built this one as well, and mine isn’t quiet at all. It’s loud and gnarly. louder than the clean signal almost immediately. Double check your build spud, because Mine is much louder than what you describe. Nasty and dirty for sure, I dig it, especially for such a simple build.

DeleteI'll have a double check of my build, there could be a solder bridge or something.
ReplyDeleteI moved on to the Shagpile tho 😄
Aha, got it working, good job I always socket transistors. Looks like the 2n3906 was a dud. Its a mean sounding loud fuzz now, which is dirty in the right way.
ReplyDeleteLower the transistor hfe to around 170 and you have a very usable octave fuzz
