I covered the 2012 NAMM Convention in Anaheim, CA and I came across many new, exciting and wonderful pieces of new technology that makes the playing of music more fun and awe inspiring. One such unit of equipment is by a company called Evertune, they manufacture a bridge for electric guitars that stabilizes and keeps strings in tune according to the musicians needs. Now, before I continue, there are other units on the market that claim to do the same thing, some manual and some electronic or computerized, but computerized units can fail and some or the mechanical units have over 100 different settings, and 99 of them are never used in actual practice. The Evertune guitar bridge is easy to use, easy to master and 100% effective. If you know how to install one, ore reach one of the Evertune listed installers, you can be up and playing in no time, and enjoying a truly useful and guaranteed solution to tuning issues.

 

EverTune

  I have been trying to write out the best description of what the Evertune guitar bridge does, and I feel that the company’s message on their site says it best:

How Evertune Works

Evertune is a concept that ensures a resonating string will always play a specific note, ie. ‘be in tune’. It does this by supplying constant tension to the string. Evertune holds one end of the string and pulls on the string with constant tension. The frequency of a resonating string has only three variables: length, mass, and tension. Again, the note a string plays only depends on three data: the length of the string, the weight of the string, and the tension of the string. Strings drift out of tune primarily because the tension changes, their mass and length are more and less constant. Evertune, holding one end of the string, will pull with constant tension, and therefore the string will stay in tune until it wants to be changed

Evertune’s first embodiment is for electric guitars. Evertune is a bridge for electric guitars. It is secured to the body of the guitar, and the ball end of the string passes through it, and over the Evertune saddle. Since Evertune is a technology that holds one end of one string, there are technically six Evertune modules in a six string guitar, one for each string; and they act completely independently. Thus, if a player breaks a string on a six string guitar, the five others are still in tune.

The Module

Each Evertune module holds one string. The magnitude of the constant tension supplied by an Evertune module can be set to any amount from 10 – 28 pounds. The tension of each Evertune module is set by a 2.5mm hex key that is supplied with Evertune and available at all hardware stores as well.

Since the tension of each Evertune module can be set by the player to any point in the range from 10 – 28 pounds, off frequency tunings such as 10 cents above and below standard 440, often used to match to off frequency samples, are part of the Evertune modules’ capabilities.

The first embodiment of Evertune creates constant tension via a spring set at a very special geometry and pulling on the bottom end of the saddle. Each Evertune module has its own spring. This spring, and spring housing, and bottom end of saddle are all embedded into the guitar and therefore invisible. The route cavity for the Evertune modules is similar to those for tremolo springs, about a half an inch longer, and a bit deeper.

The Faceplate

The six Evertune modules are all housed in an Evertune faceplate. The faceplates and Evertune modules come in four standard colors: chrome, gold chrome, black chrome, and nickel. The faceplate is aluminum to be light weight and the Evertune saddle in each Evertune module is steel.

Intonation Screws

The Evertune modules are held to the faceplate by six intonation screws in the back of the faceplate. The intonation screws are hex head and fit the same 2.5mm hex key used for tuning. Turning an intonation screw right pulls its Evertune module, which includes the saddle, back thus lengthening the string length. Turning an intonation screw left pushes the module forward, thus shortening the string length.

Action Screws

The last component of the Evertune guitar bridge are the six action screws which are screwed into the top of the faceplate. They are hex head set screws which use the same 2.5mm hex key that is used for tuning and intonation. The top of each Evertune module pushes up on the bottom of each action screw. Turning an action screw to the right makes it push its Evertune module farther down, lowering the string height. Turning an action screw to the left allows its Evertune module to rise higher, raising the string height.

Bridge Types

The Evertune guitar bridge comes in three types: the F model is low to the deck and works with guitars such as the Fender® Stratocaster® and similar guitars with a low string to deck height, the T model is like the F model and works with guitars like the Fender® Telecaster where the bridge extends around the bridge pickup, the G model works with Gibson® Les Paul®s, 335s and similar guitars that use tune-o-matic bridges and have string to deck heights that are much higher than the F and T models.

Whereas the Evertune system is available for a retrofit situation, it is also pre-installed on VGS Guitars and you can see them at the VGS Guitar site, check out the wide variety of product types and units possible. If you are a guitar player that truly wants to spend more time playing and less time tuning your axe, then Evertune is a solution for you.
