Trying to find out more about this. I know Orgy and I think Electric Wizard used them. I heard the FZ-2 could do a kind of Octavey, slightly Fender Blender kind of sound, is this true? I didn't think it was an octave fuzz at all. I like the sounds I've heard of the FZ-2 and I'm also looking for a "scrambled" sounding fuzz.
