Pro-Arte strings are our the world’s best selling and D’Addario’s premium classical guitar strings.
All Pro-Arte treble strings are sorted by a sophisticated computer-controlled laser machine which performs diameter/tension measurements and quality checks, insuring true sounding, precise trebles in every set.
Pro-Arte basses are wound using silverplated copper on a multi-filament nylon core for consistent, warm-yet-projecting tone.
