Someone here should buy this and trace it and post the circuit!
Wait a minute! Isn't this that Jen Fuzz? I've seen Jen Harmonic Booster Fuzz with 3 sliders. Cover plate says Italy.
The Jumbo Fuzz is a Big Muff knockoff. There are a few different parts values, but I don't have my schematic handy...
I like the slidepots a lot, though. Gotta love that.
