Boss OC3 Super Octave Guitar Effect Pedal
The BOSS OC-3 Super Octave guitar effect pedal gives guitarists a high-quality octave effects within a single pedal. Three modes are provided, including a new Polyphonic Octave mode, a Drive mode with distortion, and the original OC-2 mode. The versatile OC-3 has an added bonus in that it also works with bass, best when your playing up higher and its doing the octave below, very synth like.
Polyphonic mode only adds the octave effect to the lower strings and notes so you can play chords without glitches and make it sound as if your playing with a bass player. Great for jazz guitarists!! It also tracks much better than the old OC-2. Instant Rage Against the Machine if you ask me.
