**I was under the impression that you did not want to use a guitar amp. The keyboard inputs allow you to amplify an outboard source, but that is your choice. The question is: "Do you want to use your guitar amp, or travel light?"

**I'm not sure I understand this question, but if you are asking if you can use your guitar processor as a sustain pedal for the keyboard, the answer is no. The jack on your keyboard is for a dedicated momentary on/on type footswitch to trigger internal options in the Korg.

** "Electronics 101" says that you NEVER connect an amplified output to an input, so unless your guitar amp has a "line out" you should not connect it to the keyboards inputs. It sounds to me like you would like to use the functions of this guitar amp - that's great, but i see no reason to connect it to the keyboard inputs. The speakers in the Korg are probably not as powerful as the guitar amp, and are easily overloaded if not careful. The best way to utilize those inputs is when you don't have room for another amp and want to monitor keyboard and guitar through the same speakers.
Hope some of this helps.
