Andy and I have been working on the Guyatone Fuzz Monster. I did a thread on some of the Guyatone FLIP series pedals a few weeks back at diysb, and one by one, we'll dissect them, and post the traces as we go. I have a Fuzz Monster, and Hell Monster on hand, and a Funky Box on the way from Japan. I'll be cracking them open as we go down this FLIP'd journey (pardon the pun

For now, here is the schematic, courtesy of UKToecutter (Andy);

Please note that the power section has been modified for AC power. Normally, these pedals use a 12VDC wall wart, but I found that even the Guyatone branded wall warts are noisy, especially at high fuzz levels. They are crap, but, by adding a AC to DC scheme directly to a potential clone PCB (see Buy/Sell/Trade section), the noise can be pretty well killed. As for the balance of the schematic, I've gone over it with a fine tooth comb, and it matches the unit.
Go forth, and profuzzinate.
