Blast from the past. I built this pedal a few years ago and the sound would cut in and out and sputter intermittently, but when it played properly it had an amazing fuzz sound IMHO. This week, I redid all the wiring and now it works flawlessly. This by far is my favorite sounding fuzz, and second favorite GuitarPcb build , the firs being an old version of Swah autowah
