Martin MA140 Authentic Acoustic SP Light

Martin MA140 acoustic guitar strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules.

Martin starts with our high tensile-strength core wire, then tin-plate it on all six strings for added corrosion resistance; because what you dont see matters! When coupled with high quality wrap wire you get consistent true tone that you can count on song after song.

Martin Authentic Acoustic SP strings offer excellent tuning stability, corrosion resistance and great playability.
