[CES 2010] Are you tired of having to constantly tune your guitar? Well, if that’s the case, you’ll certainly want to check out EverTune, which is a bridge that keeps your guitar tuned to whatever you put it at. This works by feeding your guitar strings into an adaptive spring-tension device inside the guitar body. As each string or tuner post is loosened, the springs will compensate, and thus maintaining the tension that you set when you initially tuned the guitar. EverTune will be available on select models from certain guitar manufacturers soon, and also as an installation kit.
