Martin MA540 Authentic Acoustic Strings - SP Phosphor Bronze Light
Martin MA540 Authentic Acoustic SP Phosphor Bronze strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules. Martin starts with their 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 Martin's 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. Also available in 80/20 Bronze.
Martin's newly redesigned string packaging makes the product easier to identify and ensures a longer shelf life. Martin string packages now feature a unique color for each product family making it simple to efficiently browse their entire line and find exactly what you're looking for. Martin has also begun packaging their strings in a sealed flow wrap packet to help ensure that the strings stay fresher longer, allowing players to store strings for long periods of time without worries of tone degradation.
