Savarez Classic 520J Savarez Nylon Jaune Tension Tres Forte - set of strings

Treble strings: Rectified nylon
Strings are made from nylon, which undergoes special treatments to control elongation, elasticity and crystallinity.
The string is checked for gauge and then rectified. The surface is lightly polished to soften the feel while retaining the very slight roughness sought by many guitarists.

GRAVES strings: copper-spun nylon core, silver-plated
Spun strings are produced by wrapping nylon multifilament with silver-plated copper wire. The characteristics of the nylon multifilament and the silver-plated copper wire, as well as the manufacturing process, are decisive for sound quality, response, note holding and ease of sound emission.
