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. Available in 80/20 Bronze and 92/8 Phosphor Bronze.
Martin Authentic Acoustic SP® strings offer excellent tuning stability, corrosion resistance and great playability.
I think these are my ideal acoustic guitar string. They hold their tone for a long time, and they sound really bold. I tried 80/20s but they only sounded good for maybe two gigs, then they started sounding stale. These hold up and keep sounding great!! I like ‘em a lot!
