Electro Harmonix Micro POG

Three knob POG.
Polyphonic octave generator. You can add one octave up, two octaves up, and one octave down and blend all of them together with straight-through signal. WORKS ON CHORDS. Want your guitar to sound like a 12 string? The POG can do it—or even make it sound like an 18 string. And the POG can do a lot more than that. Destined to be a legendary EH classic.
