I picked one of these up used at GC today, and couldn't find anything about it here on TB. Its a pretty cool Big Muff style fuzz, with a Bias (Heat) and Color (Tone) that allows for a ton of super nice fuzz tones. My only concern/issue with the pedal is that the color knob has a very harsh cutoff point at around 2:30. It goes from a lot of low end, not much highs, to no low end, with a ton of highs, around that point with a couple spots in between that sound great. Here's a little demo of the setting I liked. I'm using my Fender Jazz with QPs in it, strung with Dunlop SPNs, thru a Darkglass alpha omega ultra set somewhat clean. I show my clean tone first, then alternate pick and fingers with the different pickup configurations. Have any of you used this pedal?
