Troubleshooting
Your new amp, if handled with care, should give you
trouble-free performance. If operated according to
instructions in this manual, your only maintenance
should be occasional external cleaning.
Often when an electrical component provides
poor, erratic, or no performance, it is due to minor
problems or irregularities which may be corrected
easily by someone knowing very little about elec-
tronics.
We have provided the accompanying chart for
your reference. If you have any problems at all,
please check this list first. If your problem is major
and there is definitely something wrong with the
unit, please refer to the list of GK Authorized
Service Centers included with the paperwork in the
packing box. If necessary, call your local GK Dealer
to locate you nearest GK Authorized Service Center.
You may also call our Service Department at (408)

PROBABLE CAUSES/SOLUTIONS:
Be sure all tone controls and volumes are turned up at
least part way.
Check Interconnections with speakers.
Check guitar volume, pick-ups, cord, and repair or
replace if necessary.
Be sure front panel On/Off buttons are "in", Check
footswitch cable.
Check grounding of the unit and any effects going
through the effects loop. Proper grounding is mandatory.
Repair or replace guitar cord. Make sure external effects
are patched into the Send and Return and not before the
Input. Test guitar pick-ups.
Turn off power switch and allow unit to cool off. Turn on
power again. If is comes on, make sure speaker load is
no less than 4 ohms or that unit is not affected by another
heat source (stage lighting, direct sunlight, etc.)
Check power cord, AC outlet and fuse. If all are OK or
fuse is blown, call your local GK Authorized Service
Center. Note : Be sure the correct fuse is being used.
