Introduction
Martin SP Lifespan acoustic guitar strings are engineered for extended performance and rich tone. Utilizing a proprietary treatment, these strings are designed to repel dirt, grit, and other environmental elements that can degrade string sound over time. The treatment is exceptionally thin, ensuring a natural feel and sound. SP Lifespan strings are crafted to offer enhanced durability and superior tonal quality, allowing musicians to play longer with consistent sound.

- 80/20 bronze composition provides a bright and vibrant tone.
- Light Gauge: .012, .016, .025, .032, .042, .054.
Installation Guide
Proper installation of your Martin SP Lifespan strings is crucial for optimal tone and longevity. Follow these steps to replace your acoustic guitar strings:
- Prepare Your Guitar: Loosen the tension on all old strings until they are completely slack.
- Remove Old Strings: Carefully remove the old strings from the tuning pegs and bridge pins.
- Clean Fretboard and Bridge: This is an ideal time to clean your guitar's fretboard and bridge. Use a soft cloth and appropriate guitar cleaning products.
- Insert New Strings: Starting with the lowest gauge string (high E), insert the ball end of the new string into the bridge pinhole. Secure it with the bridge pin. Repeat for all six strings.
- Wind onto Tuning Pegs: Thread each string through its corresponding tuning peg hole. Pull the string taut and then wind it around the peg, ensuring a few wraps are below the initial entry point to create a good break angle over the nut.
- Stretch and Tune: Gently stretch each string by pulling it away from the fretboard a few times. Tune the guitar to standard pitch. Repeat the stretching and tuning process several times until the strings hold their tune consistently.

Usage and Care
Optimal Performance
Martin SP Lifespan strings are designed to maintain their vibrant tone and playability for an extended period due to their protective treatment. While the treatment significantly reduces tone degradation from environmental factors, regular playing and proper care will further enhance their lifespan.
Cleaning and Longevity
To maximize the life and tone of your strings, it is recommended to wipe them down with a clean, dry cloth after each playing session. This helps remove natural oils and sweat from your hands, which can accumulate on the strings despite the Lifespan treatment. Avoid using harsh chemical cleaners, as these may compromise the string coating.
Troubleshooting
Common Issues and Solutions
- String Breaks: If a string breaks, it should be replaced immediately. Ensure proper installation techniques to prevent premature breakage.
- Loss of Tone/Dull Sound: While Lifespan strings are designed for longevity, all strings eventually lose their vibrancy. If your strings sound dull or lifeless, it is time to replace them.
- Tuning Instability: New strings require a period of stretching to stabilize. If tuning issues persist after initial stretching, re-check string installation at both the bridge and tuning pegs. Ensure strings are properly seated and wound.
