This Catalinbread Katzenkonig Fuzz is in mint condition and has velcro on the back.
The Katzenkönig by Catalinbread is a cross between a Rat Distortion and an MkII fuzz. It sings and is very saturated like a fuzz, but is also tight like a distortion. There are four control knobs on the pedal: Filter, Gain, Volume, and Input. The Katzenkönig can bring you all the way from slight overdrive, to full blown fuzz-stortion.
