Electro-Harmonix POG3 Polyphonic Octave Generator

The Electro-Harmonix POG3 pushes the classic polyphonic octave effect into bold new territory with expanded voices, deep tone-shaping controls, and modern performance features that inspire creativity on guitar and bass alike. At its core is an advanced tracking engine that delivers flawless polyphony across four octaves, letting you conjure everything from shimmering 12-string jangle to rich organ-like layers and powerful octave synth textures.

Six independent voices — including dry, two sub-octaves, a perfect fifth, and two upper octaves — can be blended with dedicated sliders and spatially positioned with pan controls into left, right, and direct outputs for immersive stereo expression. Enhanced classic controls such as ATTACK, FILTER, and DETUNE, plus new extras like INPUT GAIN, multimode filter with Q and envelope sweep, and a high-visibility OLED display, give you detailed control over your sound.

With 100 onboard presets, expression and MIDI control compatibility, and USB-C connectivity for deep editing with the EHXport app, the POG3 lets you craft unique octave-rich tones, sculpt ambient swells, create synth-like effects, or double your signal in ways that range from subtle layering to dramatic multi-voice soundscapes.
