## Description

Martin Authentic Acoustic strings provide unrivaled quality, craftsmanship, and tone for your acoustic guitar. Designed to produce true, consistent tone, these light-gauge strings provide excellent tuning stability and playability so your guitar can stand up to rigorous practice and performance schedules. Made from 92/8 phosphor bronze, these strings feature Martin's highest-quality wrap wire for enhanced longevity and durability. They are naturally corrosion resistant so they can hold up after hours and hours of playing. This pack of professional-grade guitar strings will last through long jam sessions, late-night campfire songs, and plenty of picking. To make these strings extra-durable and stable, we start with our highest-tensile-strength core wire and then tin-plate it on all 6 strings for added corrosion resistance. When coupled with our highest-quality wrap wire, you get a consistent tone that you can count on song after song. Designed to bring out your guitar's true tone, these 92/8 phosphor bronze guitar strings can be used for fingerstyle blues, Americana, country, bluegrass, ragtime, and many more styles. With this pack, you'll receive 6 light-gauge guitar strings. The low E string measures 0.054", the A string measures 0.042", the D string measures 0.032", the G string measures 0.025", the B string measures 0.016", and the high E string measures 0.012". This pack of light-gauge strings features a tension of 168.5, and they make it easy to get a rich, bright tone out of your guitar. Martin Guitar has been producing high-quality, musician-choice guitars and guitar accessories since 1833. The Martin Authentic Acoustic strings are the real deal—not an imitation. Discover your guitar's true voice with this professional-grade guitar string pack.
