Music Radar review of the ESP LTD EC 1000-ET: “No tangible tone compromises from the bridge. Unobtrusive EverTune bridge design… increasing the musicality of you and your guitar at a stroke… The EC sounds as full and aggressive as ever, with the more mellow tones of the neck EMG being pleasantly rounded, and all bereft of any metallic spring clank. You might even argue that there are resonant benefits on certain guitars.”

Guitar Player article on Joe Satriani’s Guitars.

Satriani Evertune Guitar Player MagazineJoe Satriani’s guitar tech Gary Brawer discusses the EverTune bridge in the January 2012 issue of Guitar Player Magazine.

“We recently installed Evertune bridges onto four of Joe’s non-trem guitars. There are a couple of Chickenfoot songs that have some intricate rhythm work on them and Joe was interested in trying that bridge. It was a great match. He loved how the bridges kept the chords in tune on those songs.”

The Guitar That Stays in Tune
In October, an engineer and a musician named Cosmos Lyles began selling EverTune, a guitar bridge that keeps the instrument from going out of tune no matter how hard its strings are strummed or bent.

Self-tuning guitars have been available since the late ’80s but have failed to gain traction among players because of their complexity. Gibson’s Robot Guitar system, for example, requires a rechargeable battery to power an onboard computer and motors that retune the instrument. EverTune, however, is a purely mechanical spring-and-lever system: when a string stretches or slips, the springs apply the opposing force necessary to compensate for the shift, thus maintaining the correct tension and tuning. Lyles’s solution eluded guitar builders for decades…


EverTune is garnering a lot of International attention as well.

Gitarre and Bass ReviewTranslated in English from the original German article: Download German Version >

The American Company EverTune was founded by musician and physicist Cosmos Lyles, who also had the initial idea about the constant tension system. His partner is Paul Dowd who initially was a paid consultant of Cosmos but bought into his idea from the start and since has been responsible for realizing the mechanical solution.

The heart of the system is 6 springs, which hold the strings and which by functioning like an automobile suspension ensure the same tension the whole time, regardless whether the string is influenced by mechanical or atmospheric influences (e.g. heat). Read the full article (PDF) >
