Using an AC adapter makes possible long performances with no worry about batteries going dead. GK IN Connector This connector is for connecting your guitar with a GK cable. NORMAL PU MIX Switch When Master is on, this switch determines whether or not the normal pickup sounds (or the sounds input to the GUITAR RETURN) are mixed. By mixing the normal pickup sound, you can create a sound that makes your guitar sound come alive. GUITAR OUT Jack 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.
