- finely wound and polished, handmade gut strings - brilliant sound - a wide range of sound colors Features The sheep gut core of the Oliv strings is manufactured, wound and polished in the traditional way, by hand. Musicians such as Ilya Gringolts use Oliv strings as they offer the possibility "to explore the remotest corners of sound". The sound is brilliant. Oliv strings offer the typical beautiful sound of gut strings. The tone is rich and complex. Altering the gauge by 1/4 PM changes the tension by 3%. The silver D-string is richer in overtones and has easier response than the Gold-Aluminum D-string which is included in the set. The medium set contains the following strings: E-goldsteel medium, A-aluminum 13 1/2, D-gold-aluminum 16 3/4, G-gold-silver 15 3/4. D-silver is available in four gauges.
