Fusing classic BOSS octave tones with the latest tracking technologies, the BOSS OC-5 Polyphonic Guitar and Bass Effect Octave Pedal sets a new standard in octave pedal performance. 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.High-Octane Octave PerformancePowered 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.Classic Tones with Vintage ModeThe OC-5’s Vintage mode brings you the OC-2’s iconic mono sound, coupled with improved response thanks to the new tracking engine. Dedicated level controls are provided for minus1 and minus2 octave effects and the direct sound, giving you quick access to an endless variety of sub-octave colors.Enhanced Poly ModeThe 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.Guitar and Bass Switch and Direct OutThe 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.
