Like all D'Addario ProArte strings, the trebles are sorted by a sophisticated  computer-controlled laser machine which performs diameter/tension measurements and quality checks to insure precise intonation. Composite sets feature an additional high-projection Composite 3rd string, which provides more tonal flexibility and balanced  volume transition between the basses and trebles.
 

Features Include:
   • Precise intonation
   • Clear Nylon

   • Free shipping to the continental United States
