Martin MA545 Authentic Acoustic Strings - SP Phosphor Bronze Light-Medium
Martin Authentic Acoustic Superior Performance SP strings feature higher tensile strength & tin-plated core wire on all six strings that enable a fuller & more balanced tone, quicker response & increased tuning stability. Martin's impeccable standards for acoustic guitar tone are embedded in their string design & 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.
