Just to throw in my 2 cents. I've got a boss gt10, when I've recorded I usually record directly from the GT10, into my computer with great results. You don't HAVE to mic and amp.

Doing this allows you to either capture the tones/FX from your GT10 or you can send in a dry clean signal and use software modeling tools to add FX later in your DAW.

Which DAW are you using by the way?
