D'Addario Classical Guitar Pro Arte Silver Plated/Clear Nylon Extra Hard, .029 - .045, EJ44

D'Addario EJ44 Pro-Arte Nylon Classical Guitar Strings, Extra Hard Tension

EJ44, extra hard tension, is optimal for maximum string resistance and projection without compromising tone.

Pro-Arté, the world's most popular classical strings are D'Addario's premium classical guitar string sets. All Pro-Arté treble strings are sorted by a sophisticated computer-controlled laser machine which performs diameter and tension measurements, ensuring true-sounding, precise trebles in every set. Pro-Arté basses are wound using silver-plated copper on a multi-filament nylon core for consistent and warm, yet projecting tone.

Pro·Arté classic guitar strings are just that -- classics. The treble strings are made from a harder formulation of nylon, and are precision extruded to guarantee a string that's even in diameter from one end to the other. And as an added quality-control measure, every single Pro·Arté treble string is hand-fed through a laser micrometer and sorting station to ensure that the string in your package tunes to the exact playing tension you're looking for.

Nylon is extruded in molten form; this process yields material that can vary in diameter by plus or minimum one thousandth of an inch. Though this difference is only about one fourth the thickness of a human hair, professionally trained classical guitarists can sense the contrast in string tension when the diameter varies by small amounts. The solution to the problem presented by this tension variable was to apply the latest technological advancements to the building of a sorting station, which utilizes a laser micrometer and a high-speed computer. The laser takes nearly 200 measurements on each string, compares and averages the data, and drops the measured string into the proper tension bin.

What's the end result? Every time you purchase your favorite tension of Pro-Arté classics, you get the same exact string diameter to within four ten-thousandths of an inch.

The wound strings in the Pro·Arté line are wound with silver-plated copper or 80/20 bronze wires on D'Addario's own computer-controlled automatic winding machinery and are available in 4 different tensions for classic guitar.
