Troubleshooting

Problem
The power doesn't come on
No sound/volume is low
Noise is produced
Effect not applied to the MIX/
GUITAR INPUT jacks
Check
Have the batteries run down?
Is the external device connected correctly to the
OUTPUT L jack?
Is the specified AC adaptor (PSA series; sold
separately) connected correctly?
Is the other equipment connected correctly?
Is the volume turned down on the connected
guitar amp, effects processor, or other device?
Is the GK-pickup's selection switch set to "MIX?"
Is the GK-pickup's GK Volume turned down?
Is the GK-pickup correctly installed and
connected?
Is the external device connected to the MIX/
GUITAR INPUT jack working properly?
Is the GK cable securely connected?
If a GK-compatible guitar is connected to the GK
IN connector, no effect will be applied to the MIX/
GUITAR INPUT jacks.
Action
Replace with fresh batteries.
* The life of the supplied batteries may be limited, since
its primary purpose was to enable testing.
Check the connections again.
* The unit won't switch on unless there's something
plugged into the OUTPUT L jack.
Check the connections again. Never use any AC adaptor
other than the adaptor specified.
Check the connections again.
Check the settings on the connected equipment.
When set to "GUITAR" or "SYNTH, " the necessary signals
may not be input to the unit, which may prevent sounds
from being produced.
Check to make sure the GK-pickup's GK Volume is not
lowered.
After reading the instructions in the GK-pickup Owner's
Manual, check the installation once more.
The sound of the external device connected to the MIX/
GUITAR INPUT jacks will be mixed with the sound of the
GR-S and output to the OUTPUT jacks. This means that
noise from the external device may be output.
When connecting the GK cable, insert the connector
completely, until it is locked.
If you want to apply an effect to the guitar that's con-
nected to the GUITAR INPUT jacks, don't connect anything
to the GK IN connector.
