OC-20G: Poly Octave
Features
- World’s first polyphonic octave pedal for use with GK-equipped guitars
- Octaves can be assigned to different strings for simulated guitar/bass combos
- Onboard electric and acoustic guitar simulations, plus Distortion effect
- Accommodates playing chords while using octaves
- Rugged, dual-pedal design with simple, knob-based controls
- *Note that optional GK-2AH pickup or equivalent required for use.
Thanks to the GK Pickup input, the OC-20G Poly Octave can produce octaves for various combinations of strings (like the 5th and 6th strings) while leaving the other four strings unprocessed for cool simulated guitar/bass combos—a world’s first!
Guitar Simulation and Distortion
Six guitar simulations are also provided, including three acoustic guitar simulations and three electric guitar simulations that will have audience members scratching their heads. Finally, onboard distortion can be activated to produce a thick “new-school” metal sound with bass an octave below.
*Note that optional GK-2AH pickup or equivalent required for use on both models.
