Have you seen the EverTune bridge? It’s a very clever fixed bridge which maintains tuning stability no matter what, for the life of the string. Sounds like magic, right? According to EverTune, “The benefits of this old school, all mechanical solution are that it is very rugged and reliable with only one moving part, and with all critical parts being made from high quality steel. It is also relatively reasonable in price, as opposed to servo-based (robotic) systems, and extremely effective.”
Now they’re releasing a 7-string version of the EverTune bridge. Great news for seven-stringer-slingers who don’t need a whammy bar. It’s also available in 6-string versions for Strat-style, Telecaster-style and Gibson-style axes.
