XS is breathing new life into coated strings. With its ultra-thin
film coating on every wound string and unique polymer treatment
on the plain steels, XS offers the highest level of protection
for maximum life with an uncommonly smooth feel. XS is the most
innovative string ever created.
Made with a NY Steel core, 80/20 Bronze wrap wire, and Fusion
Twist technology, these coated acoustic guitar strings have
enhanced break strength and tuning stability over standard
80/20s, in addition to a dramatically increased lifespan. This
13-56 Medium gauge set provides maximum volume and projection,
with more tension and resistance.
