Made from D'Addario's in house extruded pro-arte nylon, this set is crafted with precision to perform and pay homage to the rich mariachi musical tradition. At D'Addario we believe artists who have mastered the specialized technique to play the guitar deserve equally special strings. D'Addario offers a wide variety of ethnic instrument strings designed to the exacting specifications of our artists, instrument partners and international customers. Our computer-controlled winding machinery, laser micrometer inspection, and closed-loop tension control systems promise unrivaled quality and consistency, set after set.
