Ensure that the AC cord is fully seated and connected
to a live source.
•
Check the AC source by trying another device such as
a lamp.
Amp shuts off then after a
short time, turns back on
•
Automatic thermal protection is activating. Reduce
the volume at least 30% and keep the amplifier out of
direct sunlight or tightly enclosed spaces.
No audio (using a guitar)
•
Check the MODE switch: confirm that the yellow LED
over the intended channel is illuminated.
•
Confirm that the MASTER control and the correct
GAIN 1 or 2 controls are turned up.
•
Ensure the guitar plug is inserted fully at each end.
•
Try using a different guitar cable.
•
Check that the pickup selector switch and volume on
the guitar are set correctly.
•
Remove any cables from the RETURN jack of the
Effects Loop. If this corrects the problem, check the
effects-chain for a faulty connection.
•
Ensure that the rear panel speaker plug is fully
inserted into the INT SPEAKER jack.
MODE switch operates
backwards
•
Confirm the footswitch setting. The footswitch can
reverse the MODE setting.
Limiter, Tremolo, or
Reverb don’t work
•
Confirm the footswitch setting.
•
All effects are active with footswitch unplugged.
Reverb tone is too dark or
bright
•
Adjust the reverb TONE control.
Reverb sound has too
much “echo”
•
Adjust the DWELL control
The signal level is slowly
surging.
•
Check the tremolo effect, and increase the RATE for a
more rapid pulsation.
•
Check that the TREM control is set to its minimum
position if this sound is undesired.
Background hum
•
Ensure the guitar plug is fully inserted.
•
Try using a different guitar cable. Make sure it is
properly shielded.
•
Connect AC powered accessories to the same
receptacle as the amplifier to avoid ground loops.
If the hum goes away when you turn down the guitar:
•
Single coil pickups can be a source of hum, especially
if near RF sources like light dimmers or neon lights.
Some guitars have a mode where two pickups are in
reverse polarity to each other. This mode can often
reduce hum.
•
Check that the guitar’s cavities are well shielded.
