Does EverTune REALLY stay perfectly in tune?
In current tests of our prototypes and early production models, after one to two weeks, we might see a few strings go about 5 cents flat (which is still in tune to most ears). However, the vast majority of strings on EverTuned guitars are perfectly in tune (less than 2 cents sharp and flat) for the life of the string, through all sorts of conditions and styles of play. EverTune is a work in progress, and we continue to refine it based on feedback from our beta testers, so even this may be improved before commercial release.
