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 connectors 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).  
Tu rn in g O n th e Po w e r  
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 GK-2A  
 
(Connect the AC Adaptor)  
 
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.

N O RMAL PU MIX Sw itch  
When Master is on, this switch determines  
whether or not the normal pickup sounds (or the  
sounds input to the GUITAR RETURN) are mixed.  
AC ADAPTO R Ja ck  
This jack is for connecting an  
AC adapter (BOSS PSA-series,  
sold separately).  
By mixing the normal pickup sound,  
you can create a sound that makes  
your guitar sound come alive.  
Using an AC adapter makes  
possible long performances  
with no worry about batteries  
going dead.  
GK IN Co n n e cto r  
This connector is for connecting  
your guitar with a GK cable.  
GUITAR O UT Ja ck  
Normal pickup signals input  
through the GK-2A are output.  
When a cable is  
connected to this jack,  
the output of the  
normal pickup from the  
OUTPUT jack stops.  
GUITAR RETURN Ja ck  
O UTPUT Ja ck  
This jack is for connection to a guitar  
amp, another effects processor.  
This is an input jack for  
connecting another effects  
device, electric guitar, or  
other instrument.  
* The OUTPUT jack also doubles  
as the power switch when the  
unit is running on battery  
power. The power comes on  
when a plug is inserted into the  
INPUT jack, and goes off when  
it is unplugged. Unplug any  
connected cords when the unit  
is not in use.  
When connected to this  
jack, you can use sounds  
other than the normal  
pickup when Master is off,  
and for the Mix sounds  
when Master is on.

IMPO RTAN T N O TES  
291a  
In addition to the items listed under “USING THE UNIT SAFELY” on page 18–20,  
please read and observe the following:  
Po w e r Su p p ly : Use o f Ba tte rie s  
301 Do not use this unit on the same power circuit with any device that will generate line  
noise (such as an electric motor or variable lighting system).  
302 The AC adaptor will begin to generate heat after long hours of consecutive use. This is  
normal, and is not a cause for concern.  
303a  
The use of an AC adaptor is recommended as the units power consumption is  
relatively high. Should you prefer to use batteries, please use the alkaline type.  
304b  
Batteries should always be installed or replaced before connecting any other devices.  
This way, you can prevent malfunction and/ or damage to speakers or other devices.  
306b  
Batteries are supplied with the unit. The life of these batteries may be limited, however,
