Here is a interesting one that claims to be a fuzz with tone control. I always thought a fuzz used transistors anyway Iam sure you'll enjoy this article regardless lots of good stuff in it. Especially if your learning i believe these articles are invaluable. So anyways have fun and enjoy. If you build it let me know what its like. Cheers.
What's the best thing about fat chicks and scooters? There both fun to ride around until your mates find out!
a while back, i found this article at a local library and put the circuit on a breadboard, IIRC ... the tone section is pretty useful .... i only tried it with guitar at the time ... i may box it up sometime ...
