The OC-5 is the latest evolution of Boss's legendary octave effects, and the big news is polyphonic tracking. Where older octave pedals choked on chords, the OC-5 handles full chords and complex passages cleanly -- a genuine game-changer for rhythm players. You get independent controls for -2 octave, -1 octave, and +1 octave, letting you blend the perfect mix of sub-bass rumble and upper-octave shimmer.

The Vintage mode faithfully recreates the fat, slightly glitchy character of the original OC-2 that bass players have loved for decades. A guitar/bass switch optimizes the tracking for your instrument. It's an incredibly versatile pedal: bassists use it for synth-like sub drops, guitarists use it to fake a 12-string or add low-end heft, and everyone appreciates the rock-solid tracking. Whether you're after modern precision or vintage vibe, the OC-5 covers both sides.
