Univox Super-Fuzz-long out of production, I had to build one to hear one..im pretty sure this was used on MISFITS Legacy of Brutality, if not, its a dead ringer. (with my test rig anyway) if memory serves, its also a MUDHONEY thing. 
   The switch is a mid notch, and this box is  fuzzy as hell.......clean-up? who wants that......I added a knob to dial maximum 'Octave-up',(or dial it out) other wise, it is a faithful clone.
