Stand the test of time with strings that endure. D’Addario XT strings use groundbreaking life span technology on every string in the set to bring you enhanced pitch stability and long-lasting performance — all while preserving the tone and feel of your favorite untreated strings. These strings are made to stay, for performance that never fades away.
Maintain the power in your power chords. Strength tests prove that plain steel XT strings are up to 40% stronger than standard strings.
Stay In-tune longer
Spend less time tuning and more time playing. Torture tests have proven that XT strings stay in tune up to 131% better than standard strings.
At two whole steps higher, XT strings are still less than 75% of their breaking point. In the same setting, standard strings are at 90% of their full capacity.
