I used the search function, and couldn't find a group for this this pedal. I only recently got mine, and after some tweaking, it's everything I wanted it to be. It's not just another Muff clone; the internal pots allow one to tweak a classic sound to an extent far beyond that of the original Muff and it's various offspring. It is possible to get the range of tone from the Classic EHX BM Pi from this bad boy, and then some. My settings are: Loudness to taste, filter to 10:00, sustain maxed; and internal pots to: cliping maxed, and scoop at 12:00. This gives a sound similar to the Black Key's fuzz sounds on Rubber Factory; a compressed, yet gritty fuzz that oscillates somewhat and takes chords well. What are your settings? Thoughts? Recommendations?
