Thomastik Superflexible strings violin

This string is an advance over conventional solid strings, lying midway  in the path of evolution from the solid core to the advanced spiral core  type.

The solid core has been replaced by a cable-type structure  made up of braided steel threads. This reduces the string's stiffness,  improving its elasticity. Superflexible is incomparably responsive and  its tone seems to literally radiate from the instrument, without the  least harshness. Durability, tuning stability and purity of open fifths  are unsurpassed. Superflexible is a dependable all-round string for the  discerning musician, at home with every type of bowing and in every  musical situation. E string is a ball-end string.
