My copy of Woolly Mammoth

I have a copy of the famous Woolly Mammoth made by a friend and designed by me. We chose the name "Fuzzy Muerte" because of the draw (a pin-up of El Dia De Muertos). The sound is the same as a Woolly Mammoth with the "Wooly" sound. I don't use it a lot 'cause the output level... Now I prefer to use a Big Muff PI.

Fun, cool pedal

A kind of stripped-down version of the Fuzz Factory, this pedal is used a lot by bassists, for a modern, tight, gated fuzz with more than one possible sound. Great low-end (even sub-bass frequencies pass through). When using large amps, mine just has a slightly weaker output than the bypassed signal, which is a shame.
