Martin MA540 SP Acoustic Guitar Strings, Phosphor Bronze, Light, 12-54
If you loved MSP4100, this is the set for you!
Martin Authentic Acoustic 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 the highest quality wrap wire you get consistent true tone that you can count on song after song.
Light gauge: 12-16-25-32-42-54
