Electro-Harmonix Octavix Octave Fuzz Pedal User Guide

Quick guide from the manual

The Electro-Harmonix Octavix is a fuzz pedal featuring a frequency doubling circuit. It is designed to produce a range of distortion from light drive to intense, torn speaker fuzz tones. The pedal can be powered by a 9V battery or an external power supply.

Controls

Boost Knob

Controls the amount of fuzz. Rolling down the guitar volume while using high boost settings can produce a slightly broken-up fuzz sound.

Octave Knob

Controls the volume of the octave above signal. Turning this knob fully counter-clockwise removes the octave signal from the path.

Volume Knob

Controls the overall output signal level of the effect.

9/24 Toggle Switch

This switch selects the internal rail voltage for the circuit. Setting it to 9V provides a classic, saggy fuzz tone reminiscent of the mid-70s. Setting it to 24V provides a tighter sound and a richer octave tone.

Operation

Connect the supplied power adaptor to the 9V power jack. Plug your instrument into the INPUT jack and your amplifier into the OUTPUT jack. Use the footswitch to engage the effect; the status LED will light up when the effect is active.

Maintenance

Changing the Battery

To replace the 9-volt battery, remove the 4 screws on the bottom of the pedal and take off the bottom plate. Do not touch the circuit board while the plate is removed to avoid damaging components. To extend battery life, always disconnect the INPUT jack when the pedal is not in use.

Power Supply Requirements

The pedal draws up to 62mA at 9VDC. Use a center negative plug. Using the wrong adaptor or incorrect polarity may damage the unit and void the warranty.
