The Boss OC-2 Octave pedal uses the existing note going through it to generate 2 more notes: one octave, and two octaves down, respectively.

Subsequent Boss Octave models include:

  • OC-3 Super Octave

Controls

Image from Boss' website
  • Knob 1 - "Oct2": Sets the volume level for the signal two octaves lower than the dry signal.
  • Knob 2 - "Direct Level": Sets the volume level for the dry signal.
  • Knob 3 - "Oct1": Sets the volume level for the signal one octave lower than the dry signal.
  • Footswitch 1 - "On/Off": Toggle the pedal on or off.

Bypass:Buffered

Like all Boss pedals, the OC-2 has a buffered bypass.

General Information

This Boss pedal, is like most other octave pedals that came out in the 1980s. It is best played one note at a time, and used either to thicken melody runs, or on solos. Because the OC-2 it was not created as a polyphonic pedal, if more than one note is played, the note tracking circuitry will not be able to keep up. This tends to create sounds that are more like a cacophony than multi-octave chords being played; of course, this may be the sound you're looking for.
