Available at Acoustic Centre Melbourne

Developed in collaboration with six-time GRAMMY® winner Jason Isbell, Martin Era Jason Isbell Signature strings are built to deliver a warm, broken-in tone with a natural feel that responds beautifully to dynamic playing. Designed to reflect Jason’s preference for a traditional, expressive acoustic sound, this Artist Light set blends classic phosphor bronze character with modern string technology for exceptional balance, clarity, and touch sensitivity.

These strings combine Martin’s Lifespan corrosion treatment with a more traditional SP-style core, offering a familiar feel under the fingers while maintaining excellent longevity. Silk-wrapped ball ends protect bridge plates and string slots, making them ideal for both modern acoustics and vintage instruments. Whether you’re strumming hard or digging into nuanced fingerstyle work, this set delivers rich fundamentals, smooth highs, and consistent performance session after session.
