XS Bass

D'Addario's strings were always built for great tone. Now they're Hard to Kill.

Built for power, durability, and consistent tone, XS Bass strings deliver the reliability performers need on stage and in the studio. Through the voices of the artists, Hard to Kill highlights how the strings stay fresh, maintain their punch, and keep up with every performance—because great tone should be as relentless as the musicians who create it.

D'Addario XS

XS is the most innovative coated string ever created. Experience maximum life, a comfortably smooth feel, and a long-lasting tone that's always ready-to-play.

10 X Thinner Than a Human Hair

Ultra Thin Coating: Get lasting tone and maximum life. Our advanced coating technology allows strings to be completely protected from contaminants.

Six Sides of Stability

Prevents Slack, Powers Stability

Fusion Twist Feature: This fusion twist feature prevents slack in the twist from detuning the string. This ensures maximum tuning stability and higher break strength for our premium plain steel strings.

NY Strong

NY Steel: NY Steel is processed in D'Addario's exclusive wire facility in Farmingdale, New York. Through advanced machinery and processes, our premium high carbon steel delivers unmatched tuning stability and superior break resistance.
