The BOSS OC-5 Octave Pedal redefines what an octave pedal can do. Blending classic BOSS octave tones with modern tracking technology, it delivers the widest range, finest sound quality, and most natural playing feel ever in an octave stompbox.

Switch between Vintage and Poly modes to access legendary mono tones or rich, polyphonic textures, and explore a full three-octave span with the new octave-up feature. Whether you play guitar or bass, the OC-5 provides fat, accurate octave effects that inspire creativity on every note.
