The True Temperament Fretting System is a revolutionary approach to an age old guitar problem. One chord is in tune while another isn't. This is because of Tempered Tuning, which allows the piano to play in all keys. Before Bach they would tune it to what ever key you were playing in. 


A guitar can't quite do that because of its equal temperament fret placement. The curved frets of the True Temperament system compensate for that issue and simulate the tempered tuning far better than anything else I've experienced. With people like Steve Vai, John McLaughlin and Steve Morse on board, you know there's something to it.

These are the most in tune sounding guitars I've ever heard. Combined with the Evertune, it's magical.
