With a set of XT Phosphor Bronze Mandolin Strings on your instrument, expect to be impressed. These strings offer the midrange punch and high-end sparkle you clamor for, thanks to the phosphor bronze wrap wire. Before it’s wound onto the string, the wrap wire receives an ultra-thin coating that protects the string but feels like it’s barely there. Beyond their groundbreaking coating technology, all XT strings feature high-carbon steel cores that improve tuning stability and durability. And thanks to the company’s precision winding technology, XT Phosphor Bronze Mandolin Strings offer a consistent, reliable feel from the day you put them on to the day you take them off. It all adds up to the perfect set of strings for jazz and bluegrass players.

The evolution of XT strings
During their lifespan, EXP strings enjoyed a loyal following here at Sweetwater. Now, EXP strings have leveled up to become XT acoustic guitar strings, the next evolution of D’Addario’s world-renowned treated strings. Each string receives a groundbreaking coating for twice the protection. And since the coating is so thin, each string rings out just as loudly and clearly as an uncoated string does. If you're a fan of EXP strings, then you will love D’Addario XT strings.


Hex-core wounds, Fusion Twist steels
Inside each roundwound string in this lies an NY Steel hexagonal core — the same as you'll find on a set of your favorite NYXLs. This angular core gives the wrap wire more surface to grab on to, yielding better tone and intonation. Plain steels in this set also feature D'Addario's Fusion Twist technology. This process prevents slack in the twist, resulting in greater resistance against detuning and breaking.
D’Addario: innovative strings since 1680
When you go with D’Addario, you receive far more than a great set of strings. You’re benefiting from three centuries of string-making experience. The D’Addario family tradition began in 1680 in the tiny town of Salle, Italy, where they made assorted instrument strings for over 200 years before relocating to New York in 1905. Since then, the D’Addario family has become a leader in string innovation. They designed the modern winding machine, introduced ultra-reliable hexagonal core wires, and pioneered the colored-coded ball end movement. More than 300 years since the family started making strings, D’Addario continues to set a global standard for quality and reliability. And every day, more than 500,000 strings emerge from their USA-based workshops.
