Gibson presents the Robot Guitar. However, it does not play it's self. You play it. The guitar is a limited edition (10 per store) which has a unique feature in that it tunes it's self. You will notice the times on stage when guitarists are tuning their guitars, or having several around so they do not have to spend time tuning on stage. With the flick of a switch the guitar can now tune it's self and be ready in seconds rather then spending time your self tuning it.
Not a bad idea. I personally need a guitar that plays for me too
