HALL
This models the reverberation of a concert hall containing numerous echo
components. The operation of the knob and button is the same as with
SPRING.
Troubleshooting
The power does not turn on even when the power button is pressed
and held down.
• Is the AC adapter cord connected to the rear panel of the amp correctly?
• Is the AC adapter plugged into an AC outlet?
• Is the AC outlet switched on and working?
• Is the AC adapter damaged?
If you are using a mobile battery:
• Is the mobile battery charged?
• Has it been a while since you connected the mobile battery?
If no power is consumed after a while, the mobile battery may stop operating
and may not turn on even if you press and hold the power button on the unit.
Press the power button on the mobile battery, or disconnect and reconnect
the USB cable.
• Did you connect the USB cable slowly?
If you connect it slowly or stop midway, it may not be recognized correctly.
Quickly insert it all the way.
There’s no sound coming from the amp
• Is your guitar turned up?
• Are both ends of your guitar cable plugged into where they should be?
• Is your guitar cable working?
• Are the top panel VOLUME and GAIN knobs turned up?
• Do you have headphones or anything else plugged into the amp’s top panel
PHONES jack?
If “yes,” unplug!
• Is the amplifier model VOCODER selected with the microphone connected
to MIC IN?
VOCODER does not produce sound unless data is input to both MIC IN and INPUT.
The amp doesn’t seem very loud
• Is your guitar turned up?
• Is the top panel VOLUME or GAIN knob turned down low?
• Are you using a mobile battery?
Use a mobile battery with an output of at least 1.5A. Depending on the
mobile battery or USB Type-C used, the power may not be turned on, or the
battery may not be able to provide sufficient power.
The rhythm sound is not output
• Is the rhythm section LEVEL knob set to a low value?
• Did you switch mute on by operating the foot switch?
The rhythm tempo changes arbitrarily.
• Are you using the rhythm simultaneously with the looper?
If the rhythm is played back during loop playback, the rhythm tempo is
automatically set based on the rhythm tempo before playback and the length
of the recorded phrase.
Looper recording is not possible.
• Are you trying to record a rhythm or an input from AUX IN?
The rhythm sound and the input from AUX IN are not recorded in the looper.
There’s no looper playback sound.
• Is the LOOP LEVEL knob set to a small value?
• Is foot switch operation muted?
• Was the GAIN knob or VOLUME knob reduced during looper recording?
No sound is output from the microphone connected to the MIC IN
terminal.
• Is the microphone connected correctly?
• Is the microphone switch turned off?
• Is the TRIM knob set to a small value?
• Is the amplifier model VOCODER selected with the microphone connected
to MIC IN?
