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

EJ44, extra hard tension, is optimal for maximum string resistance and projection without compromising tone. All Pro-Arté treble strings are computer controlled by an X-Y laser microscope 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.
