Martin MA140 Authentic Acoustic SP 80/20 Bronze Guitar Strings, Light (12-54), 3-Pack

You take your choice in strings very seriously, so make the most out of your next restringing and choose C. F. Martin & Co. MA140PK3 Authentic Acoustic 80/20 HT Bronze Guitar Strings 3-Pack.

These strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules. We start with our 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 our highest quality wrap wire you get consistent true tone that you can count on song after song. Martin Authentic Acoustic SP® strings offer excellent tuning stability, corrosion resistance and great playability.

At C.F. Martin & Co., they design their strings like they design their guitars - with maximum performance, exacting tone, and playability in mind.

  • Strings designed by C.F. Martin & Co. to provide superior tone for your acoustic guitar
