Braided steel core strings for universal use. 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 The solid core has been replaced by a cable-type structure made up of braided steel threads.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. Superflexible is not only appropriate for the special timbre of viola and 'cello but seems to restore the original beauty of tone to these instruments which other strings often tend to hide. Available for full size, Medium.
