The Authentic Acoustic SP 92/8 Phosphor Bronze strings strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules. Martin started 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 their 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.
Warranty: Limited Lifetime on New & Minor Blemished Products to the original owner (excluding strings); 1 Year on Backpacker, Little Martins & Ukuleles; No warranty on Dent & Scratch items

These strings are fantastic if you like extra light strings
Martin strings are great quality, and if you prefer extra light strings then the MA530 are a fantastic choice. I have them on about half of my 12 acoustic guitars.

Martin Phosphor Bronze Sound Like Gold
