If you want to be able to keep up with synths without having to go anywhere near a keyboard, or you want to access lower notes without switching to a 5-string, then an octave pedal is the way to go.

Introduced in the early 1980s, the Boss OC-2 is widely touted to be the best brown note-provider out there; famous players like Pino Palladino, Tim Lefebvre, Juan Alderete and Janek Gwizdala have all helped to maintain the popularity of this pedal long after it was discontinued and replaced by the more refined and much less enjoyable OC-3.

This video gives an overview of 5 different analogue octave pedals to see if anything comes close to the classic synth sound of the OC-2:

  • Boss OC-2
  • MXR Bass Octave Deluxe
  • EBS Octabass
  • 3 Leaf Audio Octabvre
  • Iron Ether Subterranea
