Description: Martin MA130 SP Authentic Acoustic strings are engineered with the performer in mind and will always stand up to rigorous practice and performance schedules. The highest tensile-strength core wire is tin-plated on all six strings for added corrosion resistance; what you don't see matters as much as what you hear. When coupled with the highest quality wrap wire, these strings deliver consistent true tone you can count on song after song.

The silk and steel construction features silk fiber wrapping on the wound strings, providing a smooth, warm character with less unwanted string noise compared to traditional bronze options. These strings push your guitar toward the classical end of the spectrum in sound and feel, offering robust and well-balanced tone that's easier to play. Ideal for folk, classical fingerstyle, and lower-tension applications on traditional instruments, they excel on smaller-bodied guitars and vintage acoustics where reduced neck tension is beneficial. The custom 11.5–47 gauge offers excellent playability with reliable tuning stability and extended tonal clarity, perfect for players seeking comfort without sacrificing tone quality.
