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. We've learned a thing or two about it along the way and our game-changing Alphayue™ cello strings show off our experience well. Experiencing the joy of playing is the essence of "Alpha" cello strings - defined by beautiful balance across all strings, instant response and effortless modulation. The strings quickly perk up to their full sound potential and impress with great tuning stability. Unaffected by temperature, humidity changes and perspiration - they are also long lasting! Cello A string: carbon steel core / hydronalium wound / 4/4 size.
