Un-Strung Hero

Tonight Erik and I were lured by the sound of an Eagles cover into an Irish Pub on the beach called Jose O'Shays (no joke, that is really the name of the place). Turns out the cover band was actually a guy with a guitar and a computer that did drums and back-up vocals. Part-way through a Beatles tribute, we noticed something funny about the guy's guitar. It didn't actually have strings. There were buttons on all the frets and little metal bars across the body which he strummed as if they were strings. The best part, when he pushed a couple buttons on the back his "guitar" started sounding an awful lot like a piano. It was like watching someone who took guitar hero to a higher level. What next? Electric flutes?
