These strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules. Martin strings begins with the 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 a highest quality wrap wire you get consistent true tone that you can count on song after song.

String Gauges: 13-17-26-35-45-56
Tension: 190.9

Available and affordable


These strings are okay, wasn't my first choice but the inventory on hand was understandably very low. While I would have preferred Martin SP Flexible Core strings, or Martin Marquis, these will do for now.



They're alright


I'm using them on a Fender FA-100 acoustic. I feel like the sound is a bit dull but that's just me.



Thanks sam ash ontario


I mean they're just strings. Definitely one of my smaller purchases but I've been shopping at sam ash a long time though. Chris (butters) is an awesome tech, danny and mike have always taken really good care of me. I dont tend to shop anywhere else if I can help it.



Good strings, but prefer different brand


Thought I'd try something different. These Martin Authentic Acoustic strings have nice tone, but I still prefer the D'Addario Phosphor Bronze strings.
