For 100 years, Thomastik-Infeld has been producing fine orchestral and fretted instrument strings in our Vienna factory. Every set we make has been precision-engineered and exhaustively tested until we were satisfied that they fulfilled our intentions - and live up to your musical expectations as well. Versum Solo™ strings impress with a beautiful tonal balance: a sweet top and a warm, velvety and round bottom. With their focused sound and precise and powerful intonation they give your instrument a unique personality and offer you great versatility and expression. A vast spectrum of colors and an ideal balance across all strings provide support for the cello's lower voice while accentuating its soloistic opportunities. Cello Set, 4/4 size.
