As a long time guitar player, I will be the first to attest my annoyance for guitar tuning. Especially when you just put a fresh set of strings on the instrument. Gibson announces a new line of guitars that will use high-tech tuning features to allow the guitar to tune itself.
The Powertune system took years to develop and starts with a set of piezoelectric pickups added underneath the strumming area of the guitar, specially made for the tuning process. Unlike magnetic pickups, these will focus on each individual string, isolating the sound of teach pitch. The pickups are connected to a digital sound-processing system which allows for the tuning. — Andrew Dobrow
