Good thinking! That is definitely something I'm investigating. I wouldn't mind getting an external speaker anyways. I do have an external USB Mic now. I got all my inputs/outputs correct. I'm still just experimenting with it, haven't had a chance to play/hear my guitar yet but voice does sound very good and clear.
