Octave pedals of the past 10 years have presented guitar and bass players with a tough decision: Are you searching for that classic OC-2-style octave effect — the sound most of us guitar and bass players associate with the octave pedal — to add weight to your leads and walking lines? Or do you want modern tracking and polyphonic capabilities to help flesh out chords in a solo setting? Well, with the BOSS OC-5 Octave pedal, you don't have to choose. Whether it's thunderous mono sub-bass or strum-enriching root enhancement you're after, the OC-5 has you covered. It sports a tracking engine based on BOSS's top-tier effects floorboards. The result is one of the smoothest, lowest-latency octave effects you'll ever experience. In addition to the classic -1 and -2 octave controls, the OC-5 gives you a +1 octave dial for achieving faux 12-string textures and screaming classic lead lines. A dedicated instrument switch tailors the OC-5's tracking for either electric/acoustic guitar or bass, while a parallel Direct Out dry path preserves your input signal for running into a dedicated amp or PA. The OC-5 is the next evolution of the BOSS Octave sound.
