The Transperformance self-tuning guitar: "December 22, 2005 For most people, tuning a guitar takes three to five minutes and when they have finished, the final result is not very good. These people will love the Transperformance self-tuning guitar which takes less than a second to lock into perfect tune. While most guitars will only ever see standard tuning (EADGBE), a goodly proportion of popular music is played with alternate tunings. Just as each guitar sounds different, musicians will change the tune of a guitar to create the sound they require and that’s one of the reasons you often see a dozen or more guitars on stage at a rock concert. This single guitar can now replace all of those guitars as it can transform into any one of them at the touch of a button. The Transperformance guitar has the additional advantage of being able to change from one custom tuning to another (it holds 240 custom tunings) which can be selected from the face of the guitar or toggled with a foot pedal. As Jimmy Page (the man who wrote and played ‘Stairway to Heaven’) says of the Performer, ‘you've just got to witness what it is ... it's accurate, it's fast and it makes people's eyes pop out.'
