Boss Octave

The OC-5 introduces a new octave-up effect, which is availabl e in both Vintage and Poly modes with a dedicated +1 OCT knob. Players can 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. The OC-5 also features an evolved versio n of the smart Poly mode first introduced with the OC-3 Super Octave, letting users play full chords with octave effects. The variable Range knob restricts the effect to only the lower notes on an instrument, perfect for playing octave bass lines alongside normal chords and melodies in the higher registers. In addition, it’s now possible to isolate the octave effect to the bottom note in a chord by turning the Range knob to the “Lowest” setting.
