STRING SET FOR CLASSIC GUITAR D'Addario string set EJ-25B Flamenco ProArté. D'Addario flamenco sets are constructed using a new variant of our exclusive braided multifilament material, which dramatically improves the life and consistency of the tuning of the wound strings compared to traditional nylon cores. These games were created and tested with artists from all over the world to offer a sense of flexibility while maintaining a fast attack response, which is essential for flamenco performers.
