PowerTune: Tune any guitar instantly with a push of a button

" Imagine a guitar that tunes itself automatically, exactly how you want, whenever you want in seconds, in fact less than 2 seconds!". A modular system, the Syntax Tronical Powetune  can be fitted to pretty much any guitar of any brand and make, and claims to provide extremely accurate tuning control of 0.1 cent.

Now only if they could come with a button that could play the guitar on it's own!
