Pro-Arté Composite strings offer the traditional elegance of our Pro-Arté line, with the added benefit of an elevated bass response. The exclusive composite core bass strings in the set produce a bold, projecting low-end, providing a more influential tone than nylon basses. Paired with black nylon trebles, this set of Pro-Arté Composite strings offers a sound which is both alluring and commanding. This Flamenco Tension set delivers a flexible feel, while still maintaining the quick response that is essential for flamenco players.
