Octavix

OCTAVE FUZZ

Congratulations on your purchase of the Electro-Harmonix Octavix, a fuzz pedal with
a frequency doubling circuit. The Octavix produces a range of distortion from light
drive to over the top torn speaker fuzz tone. The frequency doubling circuit yields
classic chime and ring modulated overtones. The Octavix has control over Boost,
Octave, Volume and internal rail voltage. The rail voltage switch enables even more
tonal possibilities not found in other octave fuzz pedals.

WARNING: Your OCTAVIX comes equipped with an Electro-Harmonix 9.6DC-200BI power
supply (same as used by Boss® & Ibanez®: 9.6 Volts DC 200mA). The OCTAVIX draws up to
62mA at 9VDC with a center negative plug or runs off a 9Volt battery. Using the wrong adaptor
or a plug with the wrong polarity may damage your OCTAVIX and void the warranty.

GETTING STARTED

Connect the output plug of the supplied power adaptor to the 9V power jack. Plug
your instrument into the INPUT jack; connect your amp to the OUTPUT jack.

Sample settings:

*Tip: Playing lightly will make the octave above effect more pronounced.

BOOST KNOB

The BOOST knob controls the amount of fuzz.

*Tip: Rolling down the guitar volume with high BOOST settings gives a slightly
broken up fuzz sound.

OCTAVE KNOB

The OCTAVE knob controls the volume of the octave above signal. At fully counter
clockwise the octave above signal is removed from the signal path.

VOLUME KNOB

The VOLUME knob controls the output signal level of the effect.

9/24 TOGGLE SWITCH

The Octavix contains a rail voltage selector switch just below the OCTAVE knob. The
setting of this switch determines the power supply voltage for the entire circuit. When
set to 9, the circuit is powered by 9V, when set to 24 the circuit runs off of 24V. At
9V the pedal behaves like the classic saggy fuzz boxes of the mid 70’s. At 24V the
pedal commands a tighter sound and produces a richer octave tone.

*Note: When switching from 9 to 24 there may be volume drop before the boost in
volume. This is normal as it takes a second or two for the capacitors to charge up to
24V.

*Note: When in 24V mode, if all of the controls are at maximum it will produce
feedback which will translate into a chirping sound. This is normal.

BYPASS FOOTSWITCH & STATUS LED

The Footswitch selects whether the Octavix is engaged or in True Bypass mode.
When the effect is engaged, the LED is lit.

INPUT JACK

The ¼” jack is the audio input for the Octavix. The input impedance is 1MΩ.

AMP JACK

The ¼” jack is the audio out for the Octavix.

CHANGING THE BATTERY
To change the 9-volt battery, you must remove the 4 screws on the bottom of the
Octavix. Once the screws are removed, you can take off the bottom plate and change
the battery. Please do not touch the circuit board while the bottom plate is off or you
risk damaging a component. To extend battery life, disconnect the INPUT jack when
the Octavix is not in use. When in 24V mode the battery drain is significantly greater
than in 9V mode.

Current draw

Current draw of the OCTAVIX is 9mA when the toggle switch is set to 9 and 62mA
when the switch is set to 24.
