Boss OC-2 Octaver
The OC-2 is sub octave pedal that produces both one and two octaves below the input signal. Both octave signals (and the direct signal) have their own control knob, allowing for a seamless blend of the three tones. The OC-2 is highly regarded due to it's organic tracking and organ-like sustain.
The first OC-2's featured the name "Octaver" which was changed to "Octave" in early 1984. A second change occurred in 1985 as the colour used on the OC-2 was lightened.
Produced from April 1982 until September 2003.
Name - Octave, Octaver
