The Electro-Harmonix Nano POG Polyphonic Octave Generator is a versatile pitch-shifting pedal that expands the range and character of your electric guitar by blending your original sound with notes one octave above and one octave below. Its fast, accurate tracking allows you to play single notes, riffs, arpeggios, and full chords while maintaining a clear, natural response.

The Nano POG can add a subtle layer of octave-up sparkle, create the fuller, shimmering character of a 12-string guitar, or produce a deep, bass-like tone by emphasizing the lower octave. Blending both octave voices with the original signal can also create rich, organ-like textures and synth-inspired sounds.

Three simple controls—Dry, Sub Octave, and Octave Up—make it easy to dial in a wide variety of tones. Keep the original signal prominent for a natural sound with added depth, or turn up the octave voices for more dramatic, otherworldly effects.

Compact and easy to integrate into a pedalboard, the Nano POG works particularly well for alternative rock, indie, psychedelic music, ambient textures, and heavier guitar styles. It also pairs effectively with overdrive, chorus, and delay pedals, allowing you to build everything from thick, aggressive riffs to spacious, layered soundscapes.
