The Martin Era strings were designed to deliver exceptional tone and outstanding playability. With these strings, Martin sets a new benchmark for what modern phosphor bronze acoustic strings can achieve.
Martin Era strings blend modern innovation with refined craftsmanship. The Lifespan® treatment protects against corrosion, keeping the tone fresh and clear for longer. At the same time, the flexible core construction ensures a remarkably comfortable feel, improved fretting, and expressive, nuanced performance.
A distinctive detail is the use of silk-wrapped ball ends - inspired by classic vintage instruments and a clear nod to Martin’s long-standing tradition of artisanal string making.
The Artist Light version was developed in close collaboration with six-time GRAMMY® winner Jason Isbell. This set features a more traditional SP® core, perfectly complementing his signature sound and offering guitarists a dynamic, richly nuanced tonal character.
