PROFESSIONAL GUITAR STRINGS: Made from monel, a nickel-copper alloy, our Retro acoustic strings provide a reduced pick attack that allows the guitar’s tonewoods to be heard—not overshadowed. These solid guitar strings are the real deal, offering a true, consistent tone.
LONG-LASTING DESIGN: Discover your guitar’s true voice. These strings are designed with Martin’s naturally corrosion-resistant materials to protect the core and wrap wire and extend string life while ensuring a quality feel in every note. They’re available in extra-light, custom light, light, medium-light (“Laurence Juber’s Choice”), and medium gauges as well as in the bluegrass-inspired “Tony Rice’s Choice” string gauge.
PERFORMANCE READY: Best for rigorous practice and performance, our Retro Acoustic Guitar Strings offer enhanced longevity with a warm natural tone, and they sound great plugged in. If you have finger fatigue after playing or wish bending notes was easier, try a lighter string gauge.
VERSATILE STRINGS: String gauge is an important part of getting the best sound out of your guitar. We recommend using only our extra-light through medium-gauge strings on our guitars. Medium-gauge strings deliver more volume and are perfect for larger-bodied guitars.
THE TONE YOU DESERVE: For every handmade element we craft, we never forget why we do it: To help you set your creativity free. You’ll find a wide range of Martin strings that fit your instrument and playing style. Enjoy incredible tone, no matter what you play.
