The Warchal Avantgarde violin A string is a result of years of experiment.
Some instruments don’t work well with synthetic or gut core A strings. They may sound gritty and there can be a problem with response especially in the higher positions.
This is why many violinists, particularly Russian ones, prefer metal A strings. Warchal designed the Russian Style A for these players a few years ago.
This string however now merges the Russian style formula with our unique helical design. The helix significantly improves the longitudinal elasticity of the metal solid wire core. As a result, the Avantgarde A has more warmth and depth of tone. It keeps its high quality sound even under full attack and has a remarkably fast response.
The wavy design continues along the whole length of the string, so for some players the feeling under the finger may require a few minutes to get used to.
