Cosmos Lyles, an amateur musician working as a restaurateur, kept getting frustrated by guitars drifting out of tune mid-session from string bending and everyday wear, and started developing a fix in the mid-2000s with engineer Paul Dowd. The bridge they built, launched under EverTune in Los Angeles in 2008 and shown publicly at CES in 2010, uses a mechanical system that holds each string at constant tension regardless of how hard it's played, keeping the guitar in tune without the usual trade-offs of a locking trem. It's since been adopted as a factory option by Charvel, Cort, Jackson and Schecter, mostly on guitars aimed at high-gain, drop-tuned metal playing. We cover it through the guitars that ship with it built in. Here's what we've written.

EverTune FAQ4 questions
What is an EverTune bridge?
A mechanical bridge that keeps a guitar in tune. It uses a spring and lever for each string that maintains constant tension — when a string stretches or slips, the spring applies the opposing force needed to compensate, so temperature, humidity and playing pressure stop moving the pitch.
Who invented EverTune?
Guitarist and engineering student Cosmos Lyles came up with the device to keep his own guitar in tune, and produced a prototype with the help of engineer Paul Dowd. The mechanism is patented, and EverTune is the American company formed to make it.
How do you tune a guitar with an EverTune?
Not with the machine heads. Once the bridge is set up, tuning is adjusted with a screw on the bridge itself for each string, and the pegs stop being the working control. That is the single biggest practical adjustment for a player fitting one.
Does an EverTune stop you bending strings?
Not if it is set up for it. The bridge has adjustment zones — set fully in, a string will not bend at all, which suits rhythm and recording; set into the intermediate zone, normal bending and vibrato work while the string still returns to pitch. The zone is chosen per string.
