This idea has been around for a long time and has both good and bad points. Great in the respect of keeping the guitar in tune all the way through the gig / session - but in a way it's a form of "de-skilling" (if that's the right way to put it). What happens when it all goes wrong and your state-of-the-art tuning system falls fowl to the Murphy's 1st law of auto-tune calibration screw-ups? I'd feel safer in the knowledge that a musician actually knows how to manually tune their instrument properly. Having said that, on the one hand it's a great technological development with "uses" - but sadly, it will not make us more skillful or talented. I think the Steve Vai video a few blogs earlier shows a demonstration of Murphy's 1st Law in action :)

I don't need a self-tuning guitar. What I need is a self-tuning larynx.

Tuning is for music industry stooges.

well:gibson+new pickups+servos+some kind of batteries(or comes with a dc in to plug to a wall wart?)=the heaviest sixstring thing ever:DDD
