Troubleshooting
The power doesn’t come on.
❍ Is the external device connected correctly to the OUTPUT jack?
➔ Check the connections again.
* When running off batteries, the unit won’t switch on unless there’s something plugged
into the OUTPUT jack. This helps conserve the batteries.
❍ Have the batteries run down?
➔ Replace with fresh batteries (p. 2).
❍ Is the specified AC adaptor (PSA-series sold separately) connected
correctly?
➔ Check the connections again (p. 3, 4).
There is no sound/volume is too low.
❍ Is the other equipment connected correctly?
➔ Check the connections again (p. 3, 4).
❍ Is the volume turned down on the connected guitar amp, effects
processor, or other device?
➔ Check the settings on the connected equipment (p. 3, 4).
❍ Is the GK-2A correctly installed and connected?
➔ After reading the instructions in the GK-2A Owner’s Manual, check the
installation once more. Also, confirm that the guitar and the GK-2A have
been connected properly, using the supplied cable.
❍ Is the GK-2A’s SYNTH VOL turned down?
➔ Check to make sure the GK-2A’s SYNTH VOL is not lowered.
❍ Is the GK-2A’s selection switch set to “MIX?”
➔ When set to “GUITAR” or “SYNTH,” the necessary signals may not be
input to the unit, which may prevent sounds from being produced.
