All D'Addario Pro-Arte Nylon Core classic guitar strings deliver full-range tone with precise intonation and great projection. The clear treble strings are sorted by a computer-controlled laser machine for quality so you get the best sounding and playing strings possible. Pro-Arte silver-plated copper basses use a multi-filament nylon core for warm tone with exceptional projection.
