Violin single A-String Infeld Blue Medium tension, 4/4 scale Synthetic Core, Hydronalium

The Infeld Blue strings set give off a strong power and brightness. They are the counterpart of the Infeld Red. This set offers a balanced tone and good response throughout the violin's tonal range. They produce an open and clear sound. They settle quickly and are virtually insensitive to humidity excess.
