Martin MA150 SP Acoustic Guitar Strings, 80/20 Bronze, Medium, 13-56
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: 13, 17, 26, 35, 45, 56
