A couple of months ago I went to this place and the Entertainer was a guitarist who had a drum machine mounted next to him and a bass pedal connected to a module. He punched the drum machine, used his left foot for Bass, and played guitar with his hands and sang with his mouth Sat on a stool using his behind and balanced himself with his right foot.

It was impressive...I thought only arranger players could do such a full sounding one man show

Just an idea, and welcome aboard
