Zvex Fuzz Factory Vexter- Fuzz Pedal - AUTHORIZED DEALER

From the listing

Seller's description

The legendary Fuzz Factory!Packed with knobs that let you control everything from tight, radically fuzzy sounds that gate off instantly when you stop playing, to intermodulating oscillations that fight for control of your guitar as your notes decay, to shortwave radio sounds, ripping velcro and octave-like fuzz. Includes an on/off LED and center-negative DC power jack.The circuit is not modeled after any classic fuzz design, but should have been around when Leary was still lucid. Although the five knobs are named for the parameters over which they seem to have the most control, please don’t hold me to it. They are controls for various operating levels and biases, and basically shape you a personalized fuzz.WARNING Many ‘incorrect’ settings on this pedal squeal. This may annoy the faint-hearted. If you use the example settings, you won’t get hurt. I don’t want to see anyone hurt. Unless you’re that kind. Don’t forget to memorize or write down your favorite settings.
