The self-tuning Gibson Robot Guitar is on display at the 2008 Consumer Electronics Show (CES) in Las Vegas.
The Robot Guitar self-tunes and has open tuning with six presets that were used on such tunes as Led Zeppelin's Going to California, The Rolling Stones' Honky Tonk Women, and Jimmy Hendrix's Voodoo Child.
