Effdub Audio What the Fuzz?!Verified
Based on the Effdub What the Fuzz?!
From the post
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.
