Martin MA140 SP Acoustic Guitar Strings, 80/20 Bronze, Light, 12-54

Martin MA140 SP Acoustic Guitar Strings, 80/20 Bronze, Light, 12-54

These strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules. Martin starts with their highest tensile-strength core wire, then tin-plates 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. 

Gauges:  12, 16, 25, 32, 42 ,54

Formerly M140.
