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.
