These strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules. Start with the 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 their highest quality wrap wire you get consistent true tone that you can count on song after song. Available in 80/20 Bronze and 92/8 Phosphor Bronze. Martin Authentic Acoustic SP® strings offer excellent tuning stability, corrosion resistance and great playability.
