The Nickel Octave OC-1 can reproduce three separate tones at your choice being:
- The original tone
- A second tone one octave below the original.
- A third tone two octaves below the original
Playing along with your instrument, you can get sounds three octaves thick, and each section has a separate volume control knob!
The OC-1 Onerr features natural, clear octave sounds with stable pitch even for staccato picking sounds.
The OC-1 is not intended to be used while playing chords, but outstanding for solos.
