D'Addario EJ45C

Pro-Arte composite silver-coated copper strings for classical guitars offer a longer lifespan than traditional Pro-Arte strings. All Pro-Arte treble strings are sorted by a highly advanced, computer-controlled laser machine that performs diameter and tension measurements as well as quality controls to ensure a true, precise treble in every set. The composite sets include an additional composite third string that provides tonal options and creates a harmonic balance between nylon strings and wound strings.
