The Catalinbread Perseus is a sub-octave fuzz pedal. It has 3 knobs volume, cut, and blend. There is a switch allowing you to go either one octave down or two and from there you can blend fuzz in or out.

The pedal we have here is fully functioning. The bottom of the pedal has adhesive padding residue and the rest of the pedal has no signs of scuffing or scratching.
