Savarez 520Rs are a well developed and perfected string design utilizing quality materials and process to produce a very traditional and dependable classical guitar string set, with well rounded and even tone that clearly surpasses that of ordinary strings. The treble strings are rectified mono-filament nylon, while the bass strings are composed of pure silver thread wound on nylon multi-filament cores. The rectification process smooths and polishes the surface of the nylon mono-filaments, taking out any irregularities. The wound strings are also polished to ensure they are as smooth and consistent as the trebles. The finished string is smooth and perfectly cylindrical, with a uniform diameter over its entire length. The end result is a set of strings that can be tuned more precisely, with more harmonics and overtones native to the string. The bass sounds stronger and deeper; not thuddy, but with more precision and definition than with lesser strings. Likewise, the treble strings produce sparkling clear tones, but are not overly bright.
