Panel Descriptions

Rear Panel (Connections)
SUB CTL 1, 2/SUB EXP jack
You can control various parameters by connecting
an expression pedal (such as the separately available
Roland EV-5) or a foot switch (BOSS FS-5U, FS-6;
available separately) here (p. 33).
* Use only the specied expression pedal (Roland
EV-5, BOSS FV-500L, or FV-500H sold separately). By
connecting any other expression pedals, you risk
causing malfunction and/or damage to the unit.
* Only FOOT VOLUME can be assigned to the external
expression pedal (SUB EXP) (p. 33).
* You can’t simultaneously connect both a foot switch
and an expression pedal.
AUX IN jack
Use a stereo mini-plug to
connect your audio player.
INPUT jack
Connect your guitar.
PHONES jack
Connect headphones
(sold separately).
OUTPUT jacks
Connect these to your guitar amp or mixer.
If using a mono connection, use only the “L”
jack.
AMP CTL jack
If you’re using the Amp Control function (p. 28),
connect this to the channel switching jack of
your guitar amp.
* For some models of guitar amps, this might
not be usable.
EXT LOOP SEND/
RETURN jack
Connect to external eects
processor or amp.
LIFT/GND switch
Normally, you can leave this set to the
GND position.
If you’ve connected the EXT LOOP
(SEND/RETURN) jacks to an amp, a
ground loop may occur, producing
noise. If this occurs, you may be able
to eliminate the noise by moving this
switch to the LIFT position.
* To prevent malfunction and equipment failure, always turn down the volume, and turn o all the units before making any connections.
* When connection cables with resistors are used, the volume level of equipment connected to the inputs (INPUT , AUX IN, RETURN jacks) may be
low. If this happens, use connection cables that do not contain resistors.
