Troubleshooting

Power does not turn on
• Is an amp or speaker connected to the
OUTPUT jack?
➔ If you are using batteries, the power will
not turn on unless an amp or speaker is
connected to the OUTPUT jack. Check
the connections (p. 9).
• Have the batteries run down?
➔ Install new batteries (p. 8).
• Is the correct AC adaptor (sold
separately) connected?
➔ Check the connections once again (p. 9).
No sound/not loud enough
• Have the connections to other devices
been made correctly?
➔ Check the connections once again (p. 9).
• Has the volume been turned down on the
connected guitar amp or other device?
➔ Check the settings of the connected device.
• Could you be using a connection cable
that contains a resistor?
➔ Use a connection cable that does not
contain a resistor.
Recorded/overdubbed sound
cannot be heard or is too quiet
➔ Use the LEVEL knob to adjust the volume.
Guide tone cannot be heard/is
not loud enough
➔ Use the GUIDE knob to adjust the
volume.
➔ The guide tone will sound when:
• you've set the tempo before recording
to an empty phrase
• you play back a phrase
Recording/overdubbing ends
prematurely
➔ You have run out of memory. Delete
unneeded phrases (p. 31), and perform
the recording/overdubbing once again.

Recording does not end immediately
when you press the pedal
➔Since the phrase length is adjusted
automatically when you record with
Loop Quantize or record a phrase that is
shorter than the minimum recording
time (approximately 1.5 seconds),
recording may not stop immediately
after you press the pedal.
Recording begins immediately even
though the Auto Start function is on
➔ If there is a significant amount of noise
(for example due to distortion), that
noise may be enough to trigger the
beginning of recording. Reduce the
noise (for example by lowering the
distortion level).
The LOOP PHRASE or ONE SHOT
PHRASE indicator flashes even though
there should be time remaining for
recording
➔ In the situations listed below, temporary
memory for overdubbing (p. 28) is
allocated separately from the phrase.
Since any calculation of available
recording time must take such
temporary memory into account, the
LOOP PHRASE or ONE SHOOT
PHRASE indicator may flash.
• When a phrase is selected
• When the playback tempo is changed
• When a phrase is saved
