When some folks buy a new car, they want every possible gadget and gizmo. Others prefer simple (not to mention less expensive).
If you're in the latter group, the Martin MA170 Authentic 80/20 Bronze acoustic strings are for you. They don't have any bells or whistles—just pure tone that's the standard for bronze acoustic strings.
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.
