The Evertune Bridge
EverTune is a mechanical bridge that uses a spring and a lever for each string to keep each string in tune once tuned. Each saddle pulls on each string with constant tension, naturally maintaining tune through all conditions, even changes in temperature, heavy bending, and squeezing chords too hard.
EverTune is well suited for live gigs, recording studio, and any time musicians want to put inspiration and playing above any thoughts about their guitars performance in any environment.Basically, you never have to worry about your guitar going out of tune. Also, in this new technology, the guitar is perfectly intonated on all the frets and sounds even better.
