Making the Connections
To get the best performance from the instrument, set your amp to “Clean” (no
distortion).
When connecting the instrument to a guitar amp, make the necessary adjustments
to get the most suitable tone. When recording direct, use this with a COSM amp
(GT-3, GP-20 etc.).
• When connecting a GK cable, insert the cable completely until the connector is
securely locked. When disconnecting, press the connector’s lock while you detach
the cable.
* Always turn the amp volume down completely before connecting and disconnecting cords.
* To prevent malfunction and/or damage to speakers or other devices, always turn down the
volume, and turn off the power on all devices before making any connections.
* If there are batteries in the unit while an AC adaptor is being used, normal operation will
continue should the line voltage be interrupted (power blackout or power cord disconnection).
Turning On the Power

Be sure to observe the following order when connecting devices and switching on the power to

your equipment. By turning on devices in the wrong order, you risk causing malfunction and/

or damage to speakers and other devices.

Connect the Amp

Turn On Amp Power

* When the unit is running on battery power, the power comes on when you insert the connector
plug into the OUTPUT jack.
* Always make sure to have the volume level turned down before switching on power. Even with
the volume all the way down, you may still hear some sound when the power is switched on,
but this is normal, and does not indicate a malfunction.
* When operating on battery power only, the unit’s indicator will become dim when battery
power gets too low. Replace the battery as soon as possible.
