EverTune is an American company that produces the EverTune bridge, designed to keep guitar strings in tune.

Background

Stringed instruments, particularly guitars, have a tendency to get out of tune during playing, especially if strings are bent. In the late 1980s,

which used an onboard computer, motors, and a battery to keep the instrument in tune, but the system was complex and did not gain much marketplace acceptance, according to one report. Guitarist and engineering student Cosmos Lyles came up with a device to keep his guitar in tune, and with the help of engineer Paul Dowd produced a prototype of the EverTune bridge, which uses a spring and lever system that maintains string tension.

or the exertion of pressure on the string. On a guitar, the bridge has six springs and levers, one for each of a guitar's six strings, such that "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." In theory, the device can work with any stringed instrument, according to the inventors. The mechanism has been patented. A guitar with one installed is no longer tuned by turning the pegs at the end of the guitar's neck but rather with a screw on the bridge.

Marketing

The chief executive officer is Mark Chayet who had previously founded a manufacturing firm named ''Evermark'' which made CDs and DVDs. Chayet provided some of the initial financing for the firm, and other executives and entrepreneurs include David Weiderman, William Quigley, and Brock Pierce. The firm raised $800,000 in cash in May 2010, according to one report. One of the first guitars to have an EverTune bridge fitted in the factory is the VGS Radioactive TD-Special. A

One report suggested that EverTune will be available on a "wide range of electric guitars" in the near future and will be available as an installation kit. One report suggested there were 35 guitars with Evertune installed or about to be retrofitted with them. There are talks with guitar makers of electric guitars and basses to have the device embedded into new models and it is featured on the
