Automatic Guitar Tuner
Evertune Bridge keeps guitars in tune forever
Stringed instruments have been around for centuries, but nobody's figured out how to keep those strings in tune — until now. The breakthrough introduced at CES 2010 is called the Evertune Bridge, with individual springs constantly pulling against each string at precisely the correct tension to keep each note the same.
EverTune is based on simple mechanical principles. The EverTune bridge feeds your guitar strings into an adaptive spring-tensioner inside the guitar body.
As each string or tuner posts loosens, the springs compensate, maintaining exactly the tension you set the first time you tuned the guitar, no matter how hard or how often you play.
You’ll never again have to re-tune your guitar…unless you want to. Prefer alternative tunings? It's easy. Just tune or re-string your EverTune just like a regular guitar. Want to bend your notes? You can do that too. With EverTune, you are in control.
