Martin MA190 SP 12-String 80/20 Bronze Light Authentic Acoustic Guitar Strings

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-plate it on all 12-strings for added corrosion resistance; because what you don’t see matters! When coupled with Martin's highest quality wrap wire you get consistent true tone that you can count on song after song.
