The Octavix Octave Fuzz Pedal from Electro-Harmonix is their take on the classic '60s octave fuzz effect. It has a true bypass, frequency-doubling circuit with Boost, Octave and Volume controls, and a rail voltage toggle switch. Two 1/4' jacks connect your instrument and your amplifier.

You can regulate the output level, dial in the amount of fuzztone, and adjust the mix level of the notes an octave above your input signal with the Volume, Boost, and Octave knobs. Also, with the mini-toggle switch, you can select a 9V or 24V rail voltage for either an expanded or a compressed distortion. The Octavix runs on a 9V battery or a power supply (both available separately) and is housed in a rugged Die-Cast chassis..
