Found this this morning.
http://www.newscientist.com/backpage.ns?id=mg19626256.600Great news for ham-fisted guitarists: Gibson of Nashville, Tennessee, is launching a self-tuning electric guitar that uses piezoelectric crystals under each string to sense the frequencies of its vibrations. If a string needs tuning, a built-in chip sends an electrical signal to a tiny motor at one end, which tightens or loosens the string.
