Martin ERA JASON ISBELL PHOSPHOR BRONZE TREATED MEDIUM - set of strings

Designed to deliver exceptional tone and uncompromising playability, Martin Era™ strings set a new standard for phosphor bronze acoustic guitar strings.

The fruit of Martin Strings' expertise and innovation, they combine:

- a patented Lifespan treatment, which provides lasting protection against corrosion,

- Flexible Core construction, for enhanced flexibility and remarkable playing comfort,

- silk-wrapped ball ends, inspired by vintage instruments and testifying to Martin's heritage of string craftsmanship.

The Artist Light version was developed in collaboration with six-time GRAMMY winner Jason Isbell. It adopts a more traditional SP core, specially designed to reproduce the artist's signature timbre with authenticity and character.
