These Guyatone mini pedals are awesome, I'm a big fan. This is a big hairy fuzz: the original version was modelled after the Univox Super Fuzz. It's more of a sawtooth wave then a clipping diode under the hood, so it's got a unique juicy tone. It does a sweet low gain bluesy fuzz tone really convincingly, or max it out for some huge wall-of-sound goodness. It's got a phase flip switch and an input attenuator so you can tweak it according to the output of your pickups. Kinda ugly though?
