D'Addario XT strings use revolutionary durability technology on every string in the set to give you greater tuning stability and long-lasting performance, all while preserving the sound and feel of your favorite untreated strings. These strings are made to last, for performance that never fades. Spend less time tuning, more time playing. Tests have shown that XT strings stay in tune up to 131% better than standard strings. At two whole steps higher, the XT strings are still below 75% of their breaking point. At the same setting, standard strings are at 90% of their total capacity.
