Overview
D'Addario wraps these acoustic strings in phosphor bronze over a steel core, then seals them with an ultra-thin XS film. The coating resists corrosion without fraying or peeling, and Fusion Twist construction helps the set hold pitch.
Longevity is what you pay for here: the coating fights sweat and corrosion so tone holds up longer than bare strings. The film is thin, yet players used to uncoated sets may still feel a slight difference under the fingers.
Who it's for
Gigging and practicing acoustic players whose strings go dull from sweat. Players who restring weekly for brightness may not need a coating.
Pros and cons
- Coating extends string life
- No fraying or peeling
- Warm phosphor bronze tone
- Strong tuning stability
- Coated feel differs from bare strings
- Medium-light gauge only in this listing
- Not for electric guitars
Performance notes
Life comes from the XS film, which seals the wrap wire against corrosion while staying thin enough not to dull tone. Tuning stability comes from the steel core and Fusion Twist, which lock the strings at the ball end so they settle fast.
