BOSS OC-3, the legendary Octaver by BOSS - better than ever.
BOSS is known for being innovative and the OC-3 makes a fine example. On the OC-3 BOSS took the excellent OC-2 channel, which was and still is considered as one of the best Octaver pedals out there, and added two great modes: Drive - adds distortion, Polyphonic - cool polyphonic octave mode. The Drive mode is so organic sounding BOSS really did well with it and the Polyphonic mode is great for when you would like to play chords or set the Octaver to effect a specific range of strings.
Wether you're a bass player or an electric guitarist, BOSS got you covered since the OC-3 is working perfectly fine with either.
