Sets the standard for octave pedals. Purchased new March 2026, and only used a couple of times. I decided I liked the natural sound of my bass the best, so I’ve already sold most of my pedals. A few more to go including this one. It’s in like new shape, sounds great, here’s what Boss has to say:

Fusing classic BOSS octave tones with the latest tracking technologies, the BOSS OC-5 sets a new standard in octave pedal performance. Vintage mode provides a spot-on recreation of the legendary mono OC-2 from 1982, while Poly mode offers numerous enhancements for extended-range playing. And with the addition of an octave-up feature, a span of three octaves is now available for creative exploration. From fat, low mono sounds to octave-shifted chords and more, the OC-5 delivers the widest range, finest sound quality, and best playability in any octave stomp to date.
