Perhaps the ultimate octaver: the Boss OC-5!
Combining classic BOSS octave sounds with the latest tracking technologies, the BOSS OC-5 sets a new standard in octave pedal performance. Vintage mode offers a flawless reconstruction of the legendary mono OC-2 from 1982, while Poly mode offers numerous improvements for extended range playing. And with the addition of an octave-up function, a three-octave range is now available for creative exploration. From fat, low mono sounds to octave-shifting chords and more: the OC-5 delivers the widest range, the best sound quality and the greatest playing comfort as a contemporary octave pedal.
