D'Addario XS Phosphor Bronze mandolin strings came out of the brand's greatest breakthrough in string innovation. An ultra-thin XS film coating gives them the longest life of any D'Addario mandolin string, while preserving the warm, balanced phosphor bronze tone players rely on — all with an uncommonly smooth feel.

Built on a NY Steel core with phosphor bronze wrap wire and Fusion Twist technology, XS strings deliver incomparable break strength and tuning stability, staying in tune 131% better than standard strings. Fewer breaks, fewer tuner adjustments, and a lot more time actually playing.

This XSM11540 set is gauged 11.5-40 Custom Medium, giving you more volume and resonance than a Light set while keeping things playable. Round wound, 8 strings, suitable for all musical genres — and made in the USA at D'Addario's New York production facility. Each set arrives in a recyclable, resealable VCI bag with a code you can register to earn Players Circle points.
