This particular one just sounded good to me. It offers plain Elektra distortion-like, boring, but usable distortion with gain at zero. Fuzz rises with a turn of that knob, finally resulting in something really sick with massive made up overtones. It is basically a frequency tripler :) So i though i'd share this one too.
As a few mods, you could increase the 100n cap value at the input, as the base circuit kills a lot of low end when gain is maxed - or - when the circuit is at its best :)
A word about the circuit from Mr. Escobedo:
"This is a fuzz using a "nonselective frequency tripler", originally designed by R. Lockhart Jr. At low gains the sound can be very sweet. As the gain rises, you get a odd splatty fizz going on. And at max gain it's completely nasty. A nice, easy build."
