Electro Harmonix Octave Multiplexer
Product Description
The Electro Harmonix Octave Multiplexer is the result of many years of engineering research. It produces a sub-octave note one octave below the note you play. With two filter controls and a SUB switch, the Octave Multiplexer allows you to shape the tone of the sub-octave from deep bass to fuzzy sub-octaves.
