Okay, this thing seemed pretty cool in YouTube videos so I took the plunge. It really does not track well if you play quick notes at all. It is pretty sweet with long smooth melodic lines. I did get a good laugh out of it but overall it probably isn't worth it. I just wish that when you pluck a string, the sound comes out sooner. There is this slight pause before the note comes out and that is what drives me crazy. I am definitely going to play around with it more before decide whether to get rid of it or not.....maybe I can figure out how to make it work for me.
