Description
Introducing the Boss OC-5 Octave, a new-age addition to Boss's rich legacy of octave pedals. A fusion of classic Boss octave tones and cutting-edge tracking technologies, the OC-5 sets the bar high for octave pedal performance. The Vintage mode offers a precise recreation of the iconic mono OC-2 from 1982, while the Poly mode introduces a plethora of enhancements for extended-range playing.
The OC-5 is powered by Boss's latest real-time processing technologies, delivering a clean, accurate performance without any latency. It provides a wider range and greater polyphonic capabilities than its predecessors, making it your go-to octave pedal for every requirement.
In the Vintage mode, the OC-5 brings you the iconic mono sound of the OC-2, coupled with an improved response thanks to Boss's advanced tracking engine. The Poly mode, on the other hand, allows you to play full chords with octave effects. The variable Range knob restricts the effect to the lower notes on your instrument, perfect for creating octave bass lines alongside normal chords and melodies in the higher registers.
With the addition of an octave-up feature, a span of three octaves is now available for you to explore and create unique sounds. 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.
Key Features:
- Latest tracking technologies for accurate response and natural feel with no latency
- Vintage mode reproduces the mono sound of the original OC-2
- Poly mode for chord playing
- Octave-up effect for faux 12-string sounds and unique solo tones

Good, versatile Octave pedal
This is the modern version of the legendary Boss OC-2 pedal. Although it does offer way more settings than the OC-2, I sometimes feel that the tracking can be a bit wonky whenever you're pushing this pedal to it's limits.
Still a solid, versatile octave pedal.
Unprecedented
The bass music philosophies moved with the times because of this one of 2 pedals. (Another pedal: Electro - Harmonix Bass Big Muff)
