EJ25B is constructed using our exclusive composite multifilament stranded core material, which dramatically improves the life and tuning consistency of wound strings and delivers the flexible feel and quick attack response essential for flamenco. Includes alternate composite 3rd string for increased projection.
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.
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.
