Stock up on light acoustic strings and get the free shirt for playing style.

Buy three packs of six Martin SP Acoustic phosphor-bronze light strings (MSP4100) and get a free T-shirt celebrating the 75th anniversary of the Martin D-28 and D-18 guitars.

The strings are light gauge (from 12 to 54), 92/8 phosphor bronze acoustic guitar strings. This purchase includes one free black cotton T-shirt featuring the C.F. Martin logo with an image of the guitar headstock and body, and "D-28 D-18 75th Anniversary" screen-printed in grey displayed on the chest.

Martin SP Studio/Performance Series strings are ideal live, in the studio, or wherever maximum string life is desired. The creation of these high-performance strings was a result of Martin's research done in cooperation with specialty steel producers. Due to the development of an industry-leading ultra-high-quality steel core, Martin SP strings resist breakage better than average strings. In addition, both the core wires and the plain strings are plated with a smooth, acoustic bronze finish. Though this golden bronze finish does enhance the beauty of your guitar, its purpose is much more functional”to prolong brightness, string life, and superior tonal quality, to meet the high expectations of demanding musicians.

Amazing Deal

By Tejas

from Atlanta

I just got these strings in the mail. This is a really great deal, especially with the free commemorative shirt. The strings are also good quality, as far as I can tell. Originally, I thought the shirt was going to be too large on me because I usually wear a size Medium or a size Small, but the size Large shirt actually fits on me more like a Medium shirt does. Overall, this is an amazing deal.


Great strings and shirt.

These are some of the best sounding strings I've ever heard. I put a set on my sister's Maestro by Gibson acoustic guitar and they sound great. I let a serious musician play it the other day and he said it was the best sounding guitar he had played in a long time. That was funny to me because before I put the Martin strings on it it sounded like crap. Plus, you get a free T-shirt. Overall a great deal.
