Pro-Arte, the world's most popular classical strings are D'Addario's premium classical guitar string sets. All Pro-Arte 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-Arte basses are wound using silver-plated copper on a multi-filament nylon core for consistent and warm, yet projecting tone.

EJ43 is the lightest tension available of D'Addario's best selling Pro-Arte series. Great for beginners or experienced players with a lighter touch, they provide ease of play without sacrificing rich tone. EJ43's contain silver wound on nylon bass strings with clear nylon
trebles.
