The Strings Jason Isbell Trusts

Six-time GRAMMY® winner Jason Isbell helped design the Martin Era Artist Light strings to deliver the tone, feel, and dependability he needs on tour. Featuring a traditional SP® core for strength and familiar response, plus Lifespan treatment for long-lasting clarity, these strings are built to perform under pressure—night after night.

• Developed with Jason Isbell – Tuned to his tone and playing style.
• SP Core Construction – Strong, stable, and responsive.
• Lifespan Treated – Extends life without sacrificing feel.
• Stage-Ready Design – Holds tuning through every performance.

“I use Martin Era strings because they hold up through a lot of shows, stay in tune, and feel natural.” — Jason Isbell
