Gauges: 12 - 16 - 25 - 32 - 42 - 54

Martin Authentic Acoustic strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules. 

Martin start 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.
