Martin MA240 Authentic Acoustic Strings - SP 80/20 Bronze
Martin MA240 Authentic Acoustic SP 80/20 Bronze 12-56 Bluegrass Acoustic Guitar strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules.
Martin® Authentic Acoustic® Superior Performance SP® strings features 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! This enables a fuller and more balanced tone, quicker response and increased tuning stability. Martin’s impeccable standards for acoustic guitar tone are embedded in their string design and precision manufacturing process. That's why they make their own.
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.
