The Industry Standard in Octave Pedals
Boss - 'OC-5'

THE NEW STANDARD IN OCTAVE PEDALSMelding together iconic BOSS octave tones with the very latest in tracking technology, BOSS’s newly unveiled ‘OC-5’ has raised the bar yet again when it comes to octave pedals. Featuring two modes, ‘Vintage’ and ‘Poly’, the first, delivers an authentic replication of the classic ‘OC-2’ from 1982, whilst ‘Poly’ mode offers various clever enhancements for extended-range playing.
The ‘OC-5’ showcases a new octave-up functionality, and a range of 3 whole octaves is now on hand to take your sound to entire new levels, literally. From fat, room shaking low mono sounds to octave-shifted chords and more, BOSS’s seriously impressive ‘OC-5’ packs the broadest range, the greatest sound quality, seen in any octave pedal available today.

High-Octane Octave Performance

Guitar/Bass Switch and Direct OutPowered by the latest real-time processing technologies from BOSS, the OC-5 provides exceptional sound and playability for the most expressive octave experience ever. A key feature is the newly developed tracking engine, which delivers clean, accurate performance with no latency. The OC-5 also offers wider range and greater polyphonic capabilities than previous OC models, covering all your octave needs in one high-performance pedal.
The OC-5 lets you instantly optimize the performance of its tracking engine for either guitar or bass via a dedicated switch on the body of the pedal. And with the Direct Out jack, it’s easy to route dry and effect sounds to different destinations, such as two stage amps or discrete channels on a mixer or audio interface.
Enhanced Poly Mode

Extended Range with Octave UpThe OC-5 also features an evolved version of the smart Poly mode first introduced with the OC-3 Super Octave, letting you play full chords with octave effects. The variable Range knob restricts the effect to the lower notes on your instrument, perfect for playing octave bass lines alongside normal chords and melodies in the higher registers. And with the new tracking refinements, it’s even possible to isolate the octave effect to the bottom note in a chord—just turn the Range knob to the “Lowest” setting.
Another cool OC-5 enhancement is the new octave-up effect, which is available in both Vintage and Poly modes. Simply twist the dedicated +1 OCT knob to bring in the desired effect level. Use the octave-up effect on its own for faux 12-string sounds and unique solo tones, or blend it with the octave-down effects for extended chord voicings and super-fat leads.

BOSS - 'OC-5'Fusing classic BOSS octave tones with the latest tracking technologies, the BOSS OC-5 sets a new standard in octave pedal performance. The BOSS OC-5 provides two distinctive modes, 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.
