Vintage mode: the classic Boss octave effect

Ever since it's 1982 debut, Boss's OC-2 octave effect has left an indelible line on the guitar and bass market. The great news is, the Boss OC-5 delivers the classic OC-2 mono sound in a big way, and better than ever thanks to its improved tracking engine. Dedicated controls for your dry tone and each of the two octaves down help achieve synth-like sub bass and tight octave lead crawls without any fuss.

Poly mode: give your bassist the night off

The Boss OC-5 picks up where the OC-3 left off, with a smart polyphonic sub tracker that's able to flesh out power chords, open chords, and barre chords with bass-like root notes. It's the last piece of the puzzle for the solo acoustic performer. The OC-5 gives you a Range knob to help restrict octaves to exactly where you want them.

Octave-up effect (either mode)

A new +1 Oct control on your Boss OC-5 Octave pedal unlocks 12-string textures and classic fuzz solo tones. Best of all, this control can be used with Vintage and Polyphonic mode's -1 Oct and -2 Oct controls for a thick, impenetrable tone.
