A silicon fuzz - Radio France Fuzz

Postby hozone » 02 Jun 2015, 11:15

Hello, this is an experimental pedal i've built.
It's a standard silicon Fuzz Pedal circuit, made up using two common NPN transistors, the BC547, and the 2N5088.
I've try to "take it to the limit", to produce an extreme distorsion clipping sound.
Attached you can find the scheamtics, and a picture.

Here you can hear a demo:

many thanks for the post, davide. this thing sounds superb. really dirty and ragged with a smouldering afterglow. la classe.

Love the way that sounds, Davide. Great work. I drew up a perf/PCB layout for it. Hope to put it together over the weekend.

Went to build this over the weekend and before I got started I reviewed the layout I posted above. Realized I forgot the 1M resistor going from the base of Q1 to emitter of Q2. So here's the updated layout.
