Brand new version of a modern classic. This pedal is essentially the one octave down circuit of the 80’s Boss Japanese Octaver but with the addition of filter (which effects the octave signal) and an improved clean/direct knob based on our clean boost. At 12 o clock the filter switch is much like your standard Octave. Turn clockwise for more of a low mid bump, to cut through the mix and turn anti-clockwise to destroy the PA.
