Thomastik-Infeld Spirocore Bass Strings

Spirocore strings are a technological advancement over conventional rope-core strings because they have a more flexible spiral core made of steel, creating a higher period of vibration than other rope core strings. Equally effective when playing for arco or pizzicato.

This hi-tech core makes for effortless fingering, responsive bowing, stable tuning and a very long string life. The sound is round, even, and powerful.

Widely recognized as the reference standard and is legendary for distinctive tone and playability.

Spirocore is ideal for E extensions. It is also favoured by musicians who use pick-ups.
