How to Connect the GK-3B
2. Use the included normal guitar cable
to connect the output jack on the bass
to the GK-3B's normal pickup input
jack.

* Connect using the included normal guitar cable or a
commercially available guitar cable.
Note that the use of connection cables that introduce
additional resistance may result in lower normal
bass volume.
* This connection is necessary not only for playing the
bass's normal (straight) sound as well as the bass's
straight sound mixed with the sound from the
connected GK device, but also for connecting the
bass's ground and the GK-3B's ground. Even if you
are not going to use the bass's straight sound at all,
always make this connection because of the noise
reduction benefits it provides.
3. Turn on the power to the connected
GK device.
The Power indicator on the controller
lights up. Now, when you play your bass
you'll hear the sound of the connected
GK device.
* The power indicator lights up when the GK-3B and
the GK device are properly connected with a GK
cable and the power to the GK device is turned on.

* 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.
