Set for 3/4 contrabass, medium tension, chrome-steel on spiral steel core. Hi-tech, top grade, spiral steel core strings.

The core has greater elasticity than that of conventional strings, which means less inertia and a higher propensity to musical vibration.

The sound is full and homogenous, balanced and voluminous. The string has been calibrated to satisfy the express wish of many artists for an equally effective arco and pizzicato.

Particularly bassists with a low C extension will value this string's reliability. Spirocore is also much favored by jazz bassists because of its suitability for amplified pickup tone. Thomastik-Infeld has tackled notorious 'cello problems such as wolf notes and muting difficulties with Spirocore C and G strings in wound tungsten and silver wound.

Spirocore's hi-tech core makes for effortless fingering, responsive bowing, stable tuning and a very long string life. With Spirocore the steel string's technical possibilities have been developed to their maximum.
