Rooted in generations of D’Addario string making expertise, Pro-Arté Nylon is archetypal classical set. The special Nylon set features bass strings wound with silver-plated copper, then polished down for reduced finger noise. Coupled with clear nylon treble strings, which deliver sweet highs, Pro-Arté Nylon with Polished Basses gives you an even mellower classical guitar experience. This Hard tension set provides rich, bold tone and strong projection.
