Troubleshooting

The power doesn't come on.
Is the guitar connected correctly to the INPUT
A (MONO) jack?
Check the connections again (p. 4–p. 7).
* When running off batteries, the unit won't switch
on unless there's something plugged into the
INPUT jack. This helps conserve the batteries.
Is the plug connected to the INPUT B jack?
When using battery power, connect the plug to
the INPUT A (MONO) jack.
Have the batteries run down?
Replace with fresh batteries (p. 3).
Is the specified AC adaptor (PSA-series sold
separately) connected correctly?
Check the connections again (p. 4–p. 7).
There is no sound.
Is the other equipment connected correctly?
Check the connections again (p. 4–p. 7).
Is the volume turned down on the connected
guitar/bass amp, effects processor, or other
device?
Check the settings on the connected equipment
(p. 4–p. 7).
Is the Output Mode set correctly?
Set the Output Mode to match the connected
equipment (p. 30).
Is the Output Mode set to A: DIR / B: EFX?
No sound is output from the OUTPUT B jack
when the ON/ OFF pedal is set to OFF. Set the
Output Mode to Stereo output (out 1 or out 3)
(p. 30).
Is the effect level (E. LEVEL knob) set to minimum?
Operate the E.LEVEL knob to adjust the effect
level (p. 16).
Sound is distorted.
Are the TONE knob positioned correctly?
Sounds may become distorted with the knob at
certain settings. Turn down this knob, or turn
down the E.LEVEL knob to appropriate level. If
in spite of these measures the sound is still
distorted, lower the output level of the device
connected to the INPUT jacks, or set the Output
Mode to +4 dB (p. 30).
Pressing the MEMORY/TAP pedal
does not call up the intended
memory.
Is the proper Pedal mode set for your current
application?
The MEMORY/TAP pedal (or the MEMORY/
TAP pedal when pressed simultaneously with
ON/OFF pedal) functions differently according
to the Pedal mode settings. Use the most
appropriate setting for your particular
application (p. 29).
Is the MEMORY/TAP pedal set to the TAP
function?
If the MEMORY/TAP pedal is set to TAP
(MEMORY/TAP pedal has been pressed for
two seconds), the pedal functions as a Tap
Input pedal. To switch memories, either change
the pedal to the MEMORY switching function
by holding down the MEMORY/TAP pedal for
two seconds, or use an external pedal
(p. 14–p. 15).
The volume level of the
instrument connected to INPUT
jack is too low.
Could you be using a connection cable that
contains a resistor?
Use a connection cable that does not contain a
resistor.
