From Fuzzrocious Pedals:
KNOB JAWN is the first pedal that we know of on the market that offers BOTH analog AND digital octaving! The big knob allows you to solo or mix analog, monophonic, dirty octave up with digital, polyphonic, clean octave up and/or down. The left footswitch allows the user to jump to the opposite throw of the digital octave up/down pot (ex – if you’re set to full octave up, you can hold down the left FS to jump to full octave down…release the switch to jump back to octave up).
