D'Addario Classical Guitar Pro Arte Classical Composites Extra Hard, .029 - .047, EJ44C

D'Addario EJ44C Pro-Arte Composite Classical Guitar Strings, Extra-Hard Tension

EJ44C, extra-hard tension strings are optimal for maximum string resistance and projection without compromising tone.

Pro-Arté composite strings feature an exclusive multifilament stranded core material which delivers a powerful, but warm tone which lasts 2-3 times longer than traditional classical strings. In addition to three traditional nylon treble strings, each set contains an optional monofilament composite 3rd/G string, which provides greater projection and optimal balance between basses and trebles. All Pro-Arté treble strings are sorted by a sophisticated computer-controlled laser machine which performs diameter/tension measurements and quality checks, ensuring true sounding, precise trebles in every set.

Silver plated copper wound on an exclusive Composite core material for powerful, long-lasting tone.

Composite 3rd/G for increased projection, clear nylon 1st and 2nd strings. All laser sorted for consistent, precise intonation

Extra-hard tension, optimal for maximum string resistance and projection without compromising tone

Environmentally friendly, corrosion resistant packaging for strings that are always fresh

Made in the U.S.A. for the highest quality and performance

String Gauges: Trebles .0290, .0333, .0416 Basses .030, .036, .045

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.
