From the post
This is a mysterious little octave fuzz that apparently has a very nice, dynamic sound. I looked for the original transformer and it isn't currently available at mouser. Try a TL018 and use the 10K side. Thanks to Cozybuilder, Dino, and the others that contributed to this schem at diystompboxes
From what I've heard this will give the usual octave fuzzes a run for their money. Looks very interesting!
