Independent shopping perspective
D'Addario XS Acoustic in Medium 13-56 is a phosphor bronze set for acoustic guitar with coated wound strings and treated plain steels. Its ultrathin polymer coating is used to protect the wound phosphor bronze from corrosion and buildup, while retaining the set’s smooth feel. D'Addario rates the strings for up to 200 playing hours. High-carbon NY Steel cores and plain wire provide tensile strength, and polymer treatment on the plain strings is intended to limit slippage and help tuning remain stable.
