Boss OC-2 Octave
Boss · pedal
The Boss OC-2 Octave is a monophonic analog octave pedal capable of generating one and two octaves below the input signal simultaneously. Three controls (Direct, Oct 1, Oct 2) allow blending the dry guitar signal with one octave down and two octaves down in adjustable proportions. The monophonic tracking requires single-note playing for accurate octave generation. Originally released in 1982 and produced until 2002, the OC-2 became a vintage staple for bass-imitation tones, sub-bass textures, and funk playing. This unit is a vintage original from August 1990.
