Pro-Arte’ Dynacore strings connect the tradition and foundation of D’Addario classical string making with contemporary advancements in production technology. Dynacore basses use a revolutionary twisted multifilament nylon core processing technique to deliver unparalleled intonation, responsive attack, and crystal-clear projection, while still maintaining the essence of Pro-Arte’. Together with our precision Titanium trebles, which supply distinct balance and increased resonance in the top-end, Pro-Arte’ Dynacore strings are an exceptional blend of tradition and innovation, creating a truly unique, contemporary tone. This Extra Hard tension set provides maximum resistance and projection. D'Addario Pro-Arté Dynacore sets are constructed using our exclusive multifilament stranded core material with a revolutionary winding technique. The result is a truly unique and contemporary tone that is rich, round and full with dramatically improved string life, tuning stability and consistency. The included D'Addario Titanium trebles compliment the set with their bright and projecting tone for optimal balance across the set. Additionally, like all Pro-Arté trebles, each string is laser sorted for unsurpassed intonation consistency.
