Troubleshooting
f you suspect a malfunction, please check the following points first. If this does
not resolve the problem, contact a nearby dealer.
1. The amp isn’t powering up when the STANDBY switch is
“on”
• Is the AC/AC power supply connected to the rear panel ~AC9V jack?
• Is the AC/AC power supply plugged into an AC outlet?
• Is the STANDBY switched on?
• Could the AC/AC power supply be damaged?
2. There’s no sound
• Is your guitar turned up?
• Are both ends of your guitar cable plugged into the correct jacks?
• Is your guitar cable working?
• Could the rear panel OUTPUT LEVEL knob be turned down?
• Using the ORIGINAL VALUE LED, check the settings of the GAIN, TREBLE,
MIDDLE, BASS, VR VOLUME and CH VOLUME (on certain AMP TYPES, if the
EQ controls are all turned down, there will be little or no sound coming from the
amp due to the way the circuit of the original works). And, if a PEDAL is being
used, check the DRIVE and LEVEL settings.
• Are you in MANUAL MODE? If yes, turn the following controls above their mini-
mum setting: PEDAL DRIVE & PEDAL LEVEL [3], GAIN, TREBLE, MIDDLE,
BASS, VR GAIN & CH VOLUME.
• Could you have activated Mute on a connected foot controller? Defeat the Mute
function.
3. There’s no sound from the OUTPUT or PHONES jacks when
you use them.
• Check that the LEVEL knob that adjusts their output isn’t turned all the way
down.
4. No signal (or a distorted signal) is heard from the DIGITAL
OUT jack.
• Could the GLOBAL “DOUT LVL” be set to a low or excessively high value?
