I am starting to sort through all of the stuff I brought back from this years NAMM show. One of the most amazing products was the Evertune bridge.
EverTune is a simple concept that keeps a string in tune until it needs to be changed. It is a very exciting development in stringed instrument technology.
Self-tuning guitars have been available since the late ’80s but have failed to gain traction among players because of their complexity. Gibson’s Robot Guitar system, for example, requires a rechargeable battery to power an onboard computer and motors that retune the instrument. EverTune, however, is a purely mechanical spring-and-lever system: when a string stretches or slips, the springs apply the opposing force necessary to compensate for the shift, thus maintaining the correct tension and tuning.
EverTune is a passive, all mechanical system based on trigonometry and some rudimentary physics. Hence it is a new technology that is actually old school, its main component being a spring set in a clever position. The benefits of this old school, all mechanical solution are that it is very rugged and reliable with only one moving part, and with all critical parts being made from high quality steel. It is also relatively reasonable in price, as opposed to servo-based (robotic) systems, and extremely effective.

Bridges cost $330 plus installation — which is currently being offered for $59.95 plus shipping/insurance.
