Effects Project: PushMe PullYou - Octave Fuzz

This is a neat little octave fuzz designed by Tim Escobedo (a man who has made so many excellent effects circuits). It's a nasally fuzz tone with a prominent octave-up element.

Pretty much any transistors will work in this circuit, provided you match the polarity correctly. Note that Q1 and Q2 are NPN, while Q3 is PNP. I've tried various transistors in all positions, and everything worked. Different sorts tones, but all of them created a nice octave fuzz tone.

Here is the original schematic for those that are interested (scroll down):
