Photos: Self-tuning guitars

A Gibson Les Paul with the current version of the Performer self-tuning system for electric guitars. The user can preset the device to electronically store as many as 240 tunings. When a tuning is selected, a system of sensors and motors adjusts the tension on all six strings simultaneously. The LCD screen cut into the side of the body shows the note, octave and cent value of all six strings.
