I highly recommend this one. It's one of my favorite fuzz pedals to play with, but it's certainly not your grandfathers Fuzz Face.
True story, I used one of these and a small practice amp to run raccoons out of my attic years ago. Turned it on, dialed in the wildest noise I could find, then just left it up there overnight.
They never came back.
The Deluxe version is even cooler, it has an 8-position "Fat" switch and can switch between silicon or germanium transistors.
