Well, that particular video in my opinion was very cheesy, a drum machine and a guitar or horns does not sound like a full band,and the sound was off balance, if he played the PA80, I would agree that he would sound like a full band, don't get me wrong, I am not criticizing the musician, he is probably a very good artist, but in this video, insults the one-man band concept.
