D'Addario EJ44C Pro-Arte Composites Extra Hard Classical Guitar Strings

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.
