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.
