My niece got this "thing" the other day, I went over to see it thinking "hey maybe it can teach these kids about musical instruments," yup I was right.
It's only connection to a guitar is the shape of the controller, what a let down for me. I picked out Barracuda from the menu and attempted to "play" it, what a disaster! I need real strings and a whammy bar! Boy she just ripped into me laughing her little butt off, so I went home brought my "toy" and amp over and played Barracuda for her....... she's taking guitar lessons from a UM jazz program student now. I was right, it did help her to get into a real guitar!
