These strings are engineered with the performer in mind and they will always stand up to rigorous practice 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 highest 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.
