Martin has collaborated with Jason Isbell to develop a signature string set based on ERA strings, an upgraded standard for phosphor bronze strings. This was achieved by combining the best of Martin’s many years of expertise in string manufacturing, tone, and durability. The core and winding of the ERA strings are Lifespan 2.0-treated, a Martin-patented technology that protects against corrosion and ensures the strings last longer and retain their tone. Jason Isbell prefers a slightly stiffer feel, so the core is made from Martin’s traditional SP-Core. At the ball ends, the winding features a silk reinforcement that not only makes the string stronger but also protects delicate vintage instruments and their parts; it is also a detail that symbolizes Martin’s long tradition of innovation and forward-thinking.”
