If you have a Moogerfooger or two, this gem is going to increase their functionality like you wouldn't believe. Send LFO waveforms to control your filter...including sample and hold (wub wub wub wub). Use one expression pedal to control three parameters at once. Combine two waveforms to make new custom waveforms. There's so much more this can do. Comes with box, manual, power supply, and unit. Minty minty MINTY!! $250...steal of a deal.
