All Pro-Arté treble strings are computer controlled by an X-Y laser micrometer which performs diameter and tension measurements, ensuring true-sounding, precise trebles in every set.
All Pro-Arte treble strings are manufactured with D’Addario’s in-house extruded nylon, ensuring consistent strings with precise intonation.
Pro-Arté basses are wound using silver-plated copper on a multi-filament nylon core for consistent and warm, yet projecting tone.
