The following is an excerpt: XT NICKEL D'Addario, which has evolved guitar strings with EXL, EXP, and NYXL, has launched the latest coated strings, "XT." D'Addario has been working on developing long-life strings that combine a natural tone and touch feeling like non-coated strings, which has been considered difficult to achieve, by combining its unique latest coating technology with materials such as NYSteel and innovative elements such as Fusion Twists that have been developed so far. The XT series has achieved unprecedented longevity by coating all of the wound strings and plain strings with a high-carbon steel core using its unique coating technology. These strings finally achieve high performance in strength, pitch stability, and corrosion resistance, which were not found in previous coated strings.
