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.
