Call 631-258-2627 or email kdr@kdrmusic.com for details

The G string offers the greater range of overtones that we admire in Old Italian instruments. It gives you both depth and brilliance at the same time. This is why it is suitable for almost every violin
The D string projects well and responds clearly at every dynamic. Hydronalium is not used in the outer winding which means that there isn't a problem with corrosion caused by perspiration. The set is well balanced and there is no drop in projection on the D string
Two different A strings: The synthetic A gives improved tone and response. The metal version combines the best qualities of the Warchal metal A string line, namely the Russian A and Avantgarde. There is a short helix in the bowed area similar that found in Warchal helix E strings
The E string utilizes Warchal's legendary helix invention that makes the tone warmer and prevents whistling. The tension is precisely balanced to provide both playability as well as projection
String break-in time of about 12 minutes: We have done our best to give you a short string break-in time. After fitting Timbre strings we suggest that you play for 10 minutes using moderate dynamics. You may need to retune your strings several times during this time

Avantgarde Violin A Violin Set

Avantgarde Violin A Violin Set

We've introduced 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.
