Just to mention it... The Fuzz Factory is a GREAT fuzz, wild, weird sounds. BUT...when you adjust it, keep the volume REALLY low or you could regret it. The high frequency sounds that can suddenly blast out of there can't be good for your ears. I'm dumb, so it took me a while to realize that it is crucial that you turn the FF's volume way down while adjusting. I am getting used to tweaking it even, and still I can't always anticipate when a squeal is coming from it...and just now thought I was safely making a small tweak and this really high, loud noise came out of it, and it actually hurt my ears, and made me a little bit nauseus. Set my ears to ringing (and I already have tinnitus). So, any new owners especially, it is a really cool pedal, not knocking it at all, but some of the sounds can really get away from you!
