Set with a core of new synthetic fibre, the A- and D-string have a steel core and chromesteel wound. The G- and C-string have synthetic core and tungsten wound. The Evah Pirazzi strings are the leading product from the Pirastro company. The use of modern synthetic fibre is the basis for a new generation of strings. The A- and D-string are available since the year 2003. Since 2004 the complete set has been introduced into the market with equal big success. The very intensive and powerful sound make them the right choice for soloists. The strings allowed great nuances and offer an enormous dynamic range. They resonate beautifully and have a silvery, sweet, noble and full tone. Advantageous for these new synthetic strings compared to gut strings is the longer durability and the resistance against temperature and humidity changes. They get quickly tuned.
