Martin MA540T SP Lifespan Treated Acoustic Guitar Strings. New Martin SP Lifespan Phosphor Bronze Coated Acoustic Guitar Strings are treated to preserve the SP tone and feel for the life of the string.
Martin SP Lifespan Phosphor Bronze Coated Acoustic Guitar Strings offer a bright, rich, and warm tone. Top artists use this 92/8 composition for live performances and studio recordings due to its consistent, slightly warmer tone out of the box.
The high-tensile strength carbon steel round core wire creates increased durability, keeping your guitar in tune and in tone for longer. The proprietary Cleartone treatment on all six strings protects from dirt and oils, delivering the longest possible life for these SP strings.

Martin & Co. designs and manufactures the strings themselves. Like their guitars, each string is crafted with patience, care, and precision using only the highest quality materials to produce strings with an exacting tone and superior performance. Not only are their packaging materials minimized and 100% recyclable, but the envelopes also reduce the tarnishing effect on the strings.
