The Key Fuzz (Maestro MFZ-1 clone)
Being the Black Keys fan that I am, I had to do a clone of the Maestro MFZ-1. As heard on 'The big come up' album, it's full of fat fuzzy goodness. True bypass with polarity protection, like all my mini pedals runs off 9v adapter only (center negative 2.1mm). Current draw ~1mA.
