Thomastik-Infeld S26 Spirocore Aluminum Wound Spiral Core 4/4 Cello String - A (Medium)

Thomastik-Infeld Spirocore cello strings are the technical further development of the rope-core strings because they have a more flexible spiral core made of steel. This spiral rope has a bigger elasticity, therefore a higher period of vibration than other rope strings. The sound is round, homogenous and powerful. Spirocore is supreme. These steel strings are the latest in Thomastik's technical knowledge.
