The Superior A and D strings sound warm, round and powerful from the first second after winding up the strings. They are very well balanced and rich in overtones. They both support full forte and deep piano colors and they are very projecting and responsive. Superior strings are perfect for chamber music, orchestral playing and solos. The strings are very long-lasting which make them one of the best price-performance ratio in the market.Thickness: 0,77 mm (17,7 kp)
