Love this one. Discontinued, mint condition with velcro.

Manufacturer Info:

This Device packs a three-part polyphonic harmonizer and overdrive circuit into a compact unit that saves precious pedalboard real estate while still being completely intuitive.

Each of the Pitch Bay’s polyphonic harmonizers (“Pitch Up” and “Pitch Down”) are tunable in semitones from one octave below the root to one octave above, and every interval in between. You’ll find everything from rumbling sub-octaves, dissonant tone clusters, soaring octave-up lead sounds, to ripping NWOBHM lead guitar harmonies.  Rounding out the top row of controls is the “Gain” knob, which can go from totally clean to heavily distorted, unleashing the dirty hesher within.
