EJ49, normal tension, is D'Addario's best-selling classical set containing custom extruded black nylon trebles, preferred for its balance of rich tone, comfortable feel and dynamic projection. All Pro-Arte treble strings are computer controlled by an X-Y laser microscope 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.
All Pro-Arte treble strings are manufactured with our 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.
Semi-Polished Strings
Semi-polished classical guitar strings feature a flattened wrap wire surface for maximum finger noise reduction, making them ideal for use with microphones on stage or in the recording studio.
Polymer Extrusion Process
D'Addario's polymer extrusion line produces strings with exceptional control over string diameter and concentricity. These variables ensure the accurate tension and intonation of every string we make.
X-Y Laser Measurement
Two-axis laser micrometers continuously monitor the polymer extrusion process, ensuring precise control of string diameter and concentricity. This process results in consistent string tension and accurate intonation.
