High-Octane Octave Performance

Powered by the latest real-time processing technologies from BOSS, the OC-5 provides exceptional sound and playability for the most expressive octave experience ever. A key feature is the newly developed tracking engine, which delivers clean, accurate performance with no latency. The OC-5 also offers wider range and greater polyphonic capabilities than previous OC models, covering all your octave needs in one high-performance pedal.      


Classic Tones with Vintage Mode

Introduced in 1982, the OC-2 was the world's first modern octave pedal for guitar and bass. Still loved by players everywhere, the stomp's warm-yet-present tone sits perfectly in a mix, and its characteristic voice can be heard in many famous songs. The OC-5's Vintage mode brings you the OC-2's iconic mono sound, coupled with improved response thanks to the new tracking engine. Dedicated level controls are provided for -1 and -2 octave effects and the direct sound, giving you quick access to an endless variety of sub-octave colors.  


Enhanced Poly Mode

The OC-5 also features an evolved version of the smart Poly mode first introduced with the OC-3 Super Octave, letting you play full chords with octave effects. The variable Range knob restricts the effect to the lower notes on your instrument, perfect for playing octave bass lines alongside normal chords and melodies in the higher regist
