External Control - Korg A4 Guitar Owner's Manual

4. External Control
The A4 Guitar is equipped with two external control outputs. This function allows you to simultaneously switch the channels of one or two
amplifiers with a program change on the A4 Guitar. The open/close status of each EXT CTRL OUTjack can be set by using the External Control
utility in Edit mode. This function is useful if
you
would like to switch between your amplifier's clean and distorted channels, thereby incorpo-
rating the amplifier's built-in distortion/overdrive with the A4's other effects.
