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. We designed the Russian Style A for these players a few years ago.
We’re now introducing a string that 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.
