on Square Market   The Octave Boost is based on the classic octave-up function from vintage fuzz pedals made popular by guitarists like Jimi Hendrix. This pedal must be used in combination with another distortion, fuzz, or overdrive pedal to work properly. The pedal has two knobs- Volume and Octave. The Volume knob allows you to overload your next pedal and get increase the gain. The Octave knob controls the intensity of the octave-up effect. This will make your Fuzz Face absolutely scream and adds new textures to our Super 8-Bit Fuzz as seen in the video below.
