VOLUME

VOLUME PEDAL

Congratulations on your purchase of the Electro-Harmonix VOLUME pedal from our
ground-breaking NEXT STEP series! The VOLUME pedal has no moving parts: it does
not use a potentiometer, optics or magnetism to sweep the volume control. The
result is a responsive pedal that allows precise control over the volume of your
instrument.

GETTING STARTED
Plug your instrument into the INPUT jack; connect your amp to the OUTPUT jack.
Within seconds the EHX logo in the center of the pedal will light. Your VOLUME pedal
is now ready for use. Please note: as long as a plug is inserted into the INPUT jack, a
drain is placed on the 9V battery inside the VOLUME pedal. We recommend you
unplug the INPUT jack when the VOLUME pedal is not in use to extend battery life.

CALIBRATION
To ensure the VOLUME pedal responds to its full sweep range, it may be necessary to
calibrate the sweep of the VOLUME pedal when it is used on a different surface since
its last use. It is particularly important to calibrate if the VOLUME pedal is used on a
slanted surface. We recommend calibrating the VOLUME pedal during your first use
of the pedal.

CALIBRATION PROCEDURE

1. Place the pedal on the surface where it will be used.

2. Ensure the VOLUME pedal is sitting flat on the surface then press and
release the CALIBRATE button once; the EHX logo begins to blink indicating
the toe position has been saved.

3. While the EHX logo continues to blink, rock the pedal all the way back to the
extreme heel position and hold it there.

4. Press and release the CALIBRATE button once more.

5. The EHX logo will stop blinking to indicate that the heel position has been
saved. The calibration procedure is complete.

If you accidentally press the CALIBRATE button and the EHX logo blinks, do not press
CALIBRATE again. After approximately 7 seconds, the VOLUME pedal will stop
blinking and ignore the button press.

BYPASS VOLUME Control

The dial located on the input side of the VOLUME pedal controls the output volume
when the pedal is in bypass mode. The bypass volume gets louder as the numbers
increase on the dial.

DIRECT OUTPUT Jack

A buffered version of the input signal is sent out the DIRECT OUTPUT jack. This
output is unaffected by the position of the VOLUME pedal and remains identical to
the signal present at the INPUT jack at all times. The DIRECT OUTPUT is useful as a
source for a tuner or as a way to split the input signal.

ENTERING/EXITING BYPASS
Toggle between buffered bypass and effect mode by tipping the VOLUME pedal
forward, in the toe direction, past the flat position of the VOLUME pedal. You do not
need to tip the VOLUME pedal all the way forward; 25% of the total forward travel
will do it. The VOLUME pedal needs to return to its flat position before you can toggle
between bypass and effect mode again.

When the VOLUME pedal is in effect mode, the EHX logo in the center of the pedal
will light up. In bypass mode, the logo does not light.

POWER
Plugging into the INPUT jack activates power from the internal 9 Volt battery. The
input cable should be removed when the unit is not in use to avoid running down the
battery. If an AC Adapter is used, the VOLUME pedal will be powered up as long as
the AC Adapter is correctly plugged in.

The VOLUME pedal’s power jack is located on the same side as the OUTPUT jack. A 9
Volt AC Adapter capable of delivering at least 25mA of current at 9VDC is required to
power the VOLUME pedal. The inner ring of the 9 Volt AC Adapter must be negative,
the outer ring positive. The optional 9V power supply from Electro-Harmonix is

9.6DC-200BI (same as used by Boss® & Ibanez®) 9.6 Volts DC/200mA. The unit’s
battery may be left in or taken out when the AC Adapter is in use. The actual

current draw of the VOLUME pedal is 12mA.

CHANGING THE BATTERY

1. Locate the battery door at the front of the VOLUME pedal, under the toe
area of the top plate.

2. Remove the large black screw that holds the battery door to the case, most
coins or larger slotted screwdrivers can be used to remove this screw.

3. Connect your new 9V battery to the wired battery connector.

4. Insert the 9V battery into the battery holder clip on the battery door so that
the wired connector is on the same side of the hole in the battery door.

5. Place the battery door back into its window in the case of the VOLUME pedal
and re-install the screw.
