XT Classical strings feature an advanced corrosion resistance treatment on every wound string in the set, preserving the natural tone and feel of uncoated strings.

XT Classical string sets utilize the proprietary Composite basses and the precisely intonated trebles of D’Addario’s legendary Pro-Art strings, combining dynamic responsiveness with long-lasting performance.

The inner packaging features a re-sealable zip closure, for ease of opening as well as storage of unused strings.

Every set includes a Players Circle code for product identification, registration, and authentication. Players can collect points to get rewarded with D’Addario products and merchandise.
