Authentic Acoustic SP Custom Light Phosphor Bronze

Authentic Acoustic SP strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules. We start with our highest tensile-strength core wire, then tin-plate it on all six strings for added corrosion resistance; because what you don’t see matters!

• PROFESSIONAL GUITAR STRINGS: Discover your guitar’s true voice. These strings are designed with higher tensile strength and tin-plated core wire to enable a full and balanced tone, a quicker response, and an increased tuning stability. They’re available in extra light, custom light, light, and medium gauges.
• HIGH-QUALITY DESIGN: Made from 92/8 phosphor bronze, these acoustic strings feature top-quality bronzed-steel core wire and bronze wrap wire. They provide a well-rounded sound that is clean and balanced, making them suitable for a wide variety of music styles.
• SUPERIOR PERFORMANCE: Best for rigorous practice and performance, our phosphor bronze strings can be used for fingerpicking and flat-picking. 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.
