Overview
D'Addario has made phosphor bronze acoustic strings since 1974, and the XT version adds a coating for corrosion resistance over a NY Steel core. Phosphor bronze wrap and Fusion Twist technology give tonal versatility with added resilience.
Longer life, better pitch stability and added break resistance are the claims over standard phosphor bronze. The limitation is the contradiction in the listing, as the coating field says uncoated.
Who it's for
Regular players and gigging guitarists who change strings often and value stable pitch. Anyone who dislikes any coated feel should read the description closely.
Pros and cons
- Corrosion-resistant XT coating
- Warm phosphor bronze tone
- NY Steel core
- Better pitch stability
- Coating field conflicts with description
- Weight entry looks wrong
Performance notes
The XT coating is designed to resist corrosion while keeping the warm tone and natural feel of an uncoated string. The NY Steel core and Fusion Twist construction contribute steadier pitch and resilience. Light gauges ease fretting and bending.
