a pretty dirty fuzz pedal.
profiled direct - no amp.
added a cab and a few fx (slow subtle vintage chorus, stereo enhancer and ambience)
It has a nice Beastie Boys 'Sabotage' vibe to it (yes, I know that was a bass) but it's also great for any of your fuzzy needs.
I recommend a guitar with single coils.
