MadBean LowRider circuit, based on the Pearl OC-7. Has a one volume knob each for 2 octaves down, 1 octave down, 1 octave up, and clean. The octave up is subtle and a bit dirty. They all track very well, but as it is analog, you will get a bit of wobble as notes trail off. Black rainbow-sparkle enclosure, with a light scratch on top (visible in the picture), and velcro on the bottom.
$100 shipped ConUS.
