Martin Authentic Acoustic strings are engineered with the performer in mind and they will always stand up to rigorous play and performance schedules. We start with our highest tensile-strength core wire, then tin-plate it on all six strings for added corrosion resistance; because what you don’t see matters! When coupled with our high-quality wrap wire you get consistent tone that you can count on song after song.

Martin’s next generation Lifespan 2.0 strings are engineered using a new, patented technology only available from Martin. Developed to protect the core wire and wrap wire to prevent corrosion with compromising tone – the single most important attribute of the guitar strings. Lifespan 2.0 strings ensures they will sound better, longer than any other extended-life string on the market.

Now combined in a single value pack so you can experience both! Enjoy excellent tuning stability, great playability and feel, and superior reliability with authentic tone!
