STRING SET FOR CLASSICAL GUITAR Silverplated polished wound, includes two Sol strings: one in transparent nylon and one in composite, 1st and 2nd strings in transparent nylon. Normal Tension (28-32-36 / 40-29-35-43). The Pro-Arte Composite strings are constructed with an exclusive multi-strand in the core which improves the life and consistency of the strings. Like all Pro-Arte strings, games are classified by a highly sophisticated computer-controlled laser machine that performs diameter / tension measurements and quality control to ensure perfect intonation. The Composite games develop an additional projection. The third string provides more tonal flexibility and a balanced volume transition between bass and treble. The strings, slightly polished, reduce finger noise noticeably, making them ideal for recording.
