Martin Bronze MA140 12-52

Martin Authentic Acoustic SP® 80/20 Bronze MA140 Light

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.

92/8 Phosphor bronze strings have a higher composition of copper blended into the metal than 80/20 bronze.

Generally 80/20 bronze starts out with a bright attack and will mellow quickly, while phosphor bronze maintains a warmer more consistent tone and with greater complexity.
