Fantastic combo pedal from Keeley, combining a premium fuzz with a great pitch-shifter (not just octave). In addition to it's intended fuzzy goodness, I've used this to just drop my tuning to Eb for a tune or two and it tracks extremely well.

This pedal has been used primarily on my in-studio pedalboard, a clean and smoke-free environment. FREE SHIPPING!
