Gibson releases first self-tuning guitar.

Japanese musician Ichiro Tanaka holds Gibson's new product "Robot Guitar" at Gibson Tokyo office Monday, Dec. 3, 2007. A new electric guitar from Gibson comes with robotics technology that allows the instrument to tune itself in a matter of seconds. The technology, developed in partnership with German company Tronical, allows the guitar to recognize pitch and use its processor and six motors on its tuning pegs to tighten the strings accordingly. Gibson, based in Nashville, TN., says it's the world's first guitar-turned-robot.
