The Infeld Blue Violin E string is carbon steel which is tin plated.
Wound on an advanced synthetic core, Infeld strings are designed to cover the entire tonal spectrum, enabling players to achieve string by string tonal preferences without the headaches of uneven string to string tensions. Infeld Red violin strings are designed to create a powerful, warm and expansive tone; excellent for soloists while the Infeld Blue violin strings have a powerful but brilliant and focused tone.
Customize your sound by mixing individual strings from the two sets of Infeld strings. The Infeld Red strings offer a warmer tone, while the Infeld Blue strings are more brilliant. By using a combination of the two, players can create a set that is balanced to an individual instrument
