Overview

A new standard in octave pedals from BOSS.

Hit the switch on a BOSS OC-5, and your single-note lines suddenly feel bigger, deeper and more inspired—whether you’re laying down synthy bass hooks on guitar or adding definition to a 5-string’s low end. This next-generation octave pedal blends the character of the classic OC-2 with modern polyphonic processing, allowing everything from tight mono octave riffs to cleanly tracked chordal textures. Independent level controls for each octave voice and a dedicated Guitar/Bass switch make it easy to tailor the feel and response to your instrument. Compact, musical and incredibly responsive, the OC-5 gives players a powerful way to reshape how their parts sit in the mix.

Vintage and Poly Modes With Enhanced Tracking

The OC-5’s updated tracking engine delivers exceptional speed and accuracy, keeping fast runs, bends and wide intervals tight and glitch-free. Vintage mode recreates the beloved OC-2 voice—a warm, rubbery, analog-style octave-down sound that defined countless recordings—while Poly mode handles full chords with clarity for modern layering and harmony work. A Range control lets you isolate the octave effect to lower strings or allow full-neck response, perfect for balancing foundational lows with clean upper-register detail. With -2, -1 and +1 octave voices available, you can move from subtle reinforcement to massive multi-octave stacks that feel bold and expressive.

Guitar/Bass Switch and Flexible Routing

To deliver consistent performance across different instruments, the OC-5 includes a dedicated Guitar/Bass switch that optimizes tracking behavior for each range. Bassists gain improved low-frequency stability, while guitarists benefit from articulate response across the fretboard. Separate Direct Out and Main Out jacks make it easy to split dry and effected signals for bi-amping, parallel processing or sending independent feeds to front of house. Add in buffered bypass and simple 9V operation, and the OC-5 integrates seamlessly into any pedalboard—from streamlined rehearsal rigs to fully routed touring setups.

A Compact Octave Pedal With Stage-Ready Flexibility

For guitarists and bassists who want a single pedal that covers classic mono octave tones, clean polyphonic layers and tight modern tracking, the BOSS OC-5 delivers a rare combination of simplicity and depth. Its blend of vintage character and contemporary precision makes it a versatile tool for players exploring new textures or reinforcing their core sound. Durable, intuitive and unmistakably musical, it’s a pedal that elevates any board—offering octave power that grows alongside your style.
