I know it works for some, like the White Stripes and Black Keys, but my newly purchases zvex fuzz factory was all fizz and little fuzz. Now, im seeing this come up in my search for solutions that certain amps -- like old fenders -- dont take all fuzz pedals well, lets in too much high-gain fizz over other frequencies (sounds about right). So how to I figure what will at least work without having to spend $$$ in trial and error (as for liking it, thats my own problem)? Why does a big muff work but the fuzz factory doesnt? Im seeing 'Hi-cut pedals for fenders' come up a lot... And, can you guys recommend some good fuzz, od, and boost pedals for a sf super reverb?
