I got this as an early XMAS gift from my Dad. He ordered it from Musictoyz and wanted me to try it to make sure I liked it. Uh, yeah. It's awesome. I've seen threads on this before, but I've got to put my .02 in. I was happy to find that it also works great behind my Picture Wah. Many fuzzes do not match up well here, due to impedance mismatches. I guess since this is IC instead of transistors that's less of an issue. Anyway, the fuzz sounds huge and massive with Strats, McCarty, and Monaco Elite P-90. Tremendous sustain and somehow keeps the timbre of the pickup being used. Great job by Erik for reviving this version of the Big Muff! Oh how I love muff!
