PS-009 (Multi Octaver)

Effect Information

Guyatone PS-009 Multi Octaver is a great octave pedal, made in Japan in
the 80s. The PS-009 is similar to Pearl OC-07 Octaver, sometimes
thought of as a “poor man’s Pearl.” Don’t listen to people that say
that! Nothing “budget” about this pedal. Heavy die cast enclosure, built
to last. Has a nice extra “Octave Only” output, really handy if you
want to send just the octaves to a separate amp (a feature the Pearl does not have).


  • Lower 1 controls the volume of a tone 1 octave below the input signal

  • Lower 2 controls the volume of a tone 2 octaves below the input signal
  • Upper controls the volume of a tone 1 octave above the input signal

“But, be warned: the octaves this pedal
generates are (intentionally) very distorted and will make your guitar
sound very synth-like … so the PS-009 is not for the unadventurous.
Requires a 9v, center-negative DC power supply or can be powered by a 9v battery.”
