Boss OC-5 Polyphonic Guitar/Bass Octave Pedal

The Boss OC-5 Octave Pedal delivers rich, powerful octave tones with modern tracking and expanded versatility for both guitar and bass. Combining classic Boss octave sounds with advanced polyphonic performance, the OC-5 lets you add depth, weight, and texture to your tone like never before.

In Vintage mode, you get the iconic OC-2-style monophonic octave tone—tight, punchy, and perfect for funk, leads, and classic octave effects. Switch to Poly mode to unlock smooth, glitch-free tracking across chords, with adjustable range so you can apply the octave effect only to your lowest notes while keeping higher notes clean and defined.

Dedicated controls for Direct Level, Octave Up, and Octave Down (-1 and -2) give you full command over your sound, from subtle thickening to massive, synth-like tones. A built-in bass mode optimizes performance for low-frequency instruments, making the OC-5 a great choice for both guitarists and bass players.
