MA550T Lifespan 20 Phosphor Bronze Medium Authentic Acoustic Guitar Strings

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. Martin invested two years developing these Lifespan 2.0 strings to ensure they will sound better, longer than any other extended-life string on the market.

This is a 92/8 Phosphor Bronze Medium pack.
