The XT classic comes with D'Addario's Pro-Arté composite bass strings for a rich and powerful tone with plenty of warmth, generating a perfect tonal transition between the spun and unspun strings. The winding is treated with D'Addario's protective microcoating, a super thin coating that effectively repels dirt and sweat. This is a set of strings with unrivaled dynamic response, with perfect intonation and long-lasting durability.
