One of the most popular boutique fuzz pedals is the Fuzz Factory by ZVex Effects. This cool fuzz pedal came out in the mid 1990s and turned the traditional fuzz pedal market on its side.
Taking their starting point from a germanium based Fuzz Face, the folks at ZVex created a truly unique fuzz that did way more than just fuzz up and distort your guitar sound. Fuzz Factories twisted, sputtered, howled, grunted and choked the tone, with truly unbelievable sonic results. And these sputtery fuzzboxes also begat an entire subculture of fuzz makers and enthusiasts.
