Evertune Bridge Demonstration

EverTune is a simple concept that keeps a string in tune until it wants to be changed. It is a very exciting development in stringed instrument technology. It 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 reliab
