CowboyRobot writes "With the TransPerformance Performer you push a button to activate a mechanical re-tensioning of the strings to any of a few hundred tunings, 'accurate to within 2 cents over the entire tuning range', in a couple of seconds. They can even refit your existing guitar. There's a long audio interview with Jimmy Page on the site. It's funny to hear him speak."
