Pro-Arte Composites are crafted using a unique multifilament stranded core material, which significantly improves the lifespan and tuning consistency of the wound strings. Like all Pro-Arte strings, the trebles undergo a sophisticated sorting process using a computer-controlled laser machine.

This machine accurately measures diameter and tension, while also performing quality checks to ensure precise intonation. Additionally, the composite sets include a high-projection Composite 3rd string that provides greater tonal flexibility and a balanced volume transition between the bass and treble strings.
