Old meets new in the most versatile octave pedal yet. The Boss OC-5 is the new flagship octave pedal and sets a new benchmark. Building upon everything good about the previous models, the OC-5 incorporates innovative upgrades to deliver the new industry-standard in octave effects. These include a new dedicated octave-up control, Guitar/Bass selector switch, and variable range control to choose which notes get harmonised. The biggest upgrade, however, is the elimination of latency, so you don't need to worry about any delay between you playing the note and the octave sounding. Boss have upped the game with the OC-5, and created the most definitive octave harmoniser yet.
