Martin MA140 SP 80/20 Bronze Light Authentic Acoustic Guitar Strings

Martin MA140 SP 80/20 Bronze Light Authentic Acoustic guitar 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-plate it on all six strings for added corrosion resistance; because what you don’t see matters. When coupled with the highest-quality wrap wire, you get consistent true tone that you can count on song after song.

This is a 80/20 Bronze Light set.
