D'Addario XT: The next evolution in guitar strings. Designed to stand the test of time, 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.

 D'Addario XT Phosphor Bronze Acoustic Guitar Strings features:

- A thin, hydrophobic coating protects every string in the set from the corrosive effects of sweat and humidity.
- Made with the same high carbon steel found in NYXL and Nickel Bronze, XT strings deliver enhanced break resistance and tuning stability.
- XT strings feature an extended life span treatment that preserves the natural tone and feel of newly made strings.
- From wire drawing to micro coating, we control every aspect of the string making process to ensure every set performs to your standards.
- Inner packaging is marked with a Players Circle code for product identification, registration, and authentication apart from the outer packaging. Players can collect points to get rewarded with free D’Addario product and merchandise.
