Martin 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 does matter! When coupled with our highest quality wrap wire you get consistent true tone that you can count on song after song.
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.
