The Martin MA180 is a full set of Authentic Acoustic SP® strings wound specifically for 12-string acoustic guitars. If you play a 12-string and want a reliable, tried-and-true set at an extra light gauge, these are a solid choice — easy on the fingers and designed to stay in tune under the added tension a 12-string puts on any set of strings.
Martin builds these with their highest tensile-strength core wire, tin-plated on all six primary strings for added corrosion resistance. The 80/20 bronze wrap wire delivers a clear, bright tone that's characteristic of the alloy — open and responsive right out of the pack. The extra light gauge (.010–.047 on the primary strings) keeps overall tension manageable, which is especially welcome on a 12-string where you're dealing with twice the string load.
The full 12-string gauge set breaks down as follows: E .010/.010, B .014/.014, G .023/.010, D .030/.012, A .039/.018, E .047/.027. That covers both the primary and octave/unison strings across all six courses.
