Boss has announced the OC-5 Octave, the latest generation of the long-running OC series of octave pedals for guitar and bass. Offering the most advanced Boss octave performance to date, the OC-5 features a new Vintage mode, polyphonic enhancements and an octave-up feature for extended range. 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 leads.
