Martin MA180 12-String SP Authentic 80/20 Extra Light Guitar Strings, 10-47

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. Available in 80/20 Bronze and 92/8 Phosphor Bronze.

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