Martin Strings : Martin Authentic Treated Custom Light 11-52 80/20

Martin’s next generation Lifespan 2.0 strings are engineered using a new patented technology only available from Martin. This technology was developed to protect the core wire and the wrap wire to prevent corrosion without compromising tone – the single most important attribute of the guitar strings. Authentic Acoustic Lifespan 2.0 strings look better sound better and feel better providing a smooth playing experience that reduces finger drag. We invested two years developing our next generation Lifespan 2.0 strings to ensure they will sound better longer than any other extended-life string on the market. Available in 80/20 Bronze and 92/8 Phosphor Bronze.
