Big Ear NYC Chaka Octave Fuzz
Of course, with the octave effect on it's own footswitch, he can also be one of the meanest stand-alone fuzz pedals you've ever heard.
And don't worry about that classic "I lost all my low end" problem. That won't happen with CHAKA. Features hand-matched germanium diodes (on the octave side), NOS metal can transistors, and LED clipping!
