En allsidig stålstreng, favorisert av mange bassister!

These top-grade, hi-tech Thomastik-Infeld Spirocore S42 Upright Double Bass Strings (4/4 Medium) are renowned for their ease of playability and their distinctive sound.

“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.”
— Thomastik-Infeld

The Spirocore S42 strings deliver a full, balanced and voluminous sound thanks to their flexible multi-wire spiral rope core. Lower inertia allows the strings to vibrate more freely, making them equally effective for both arco and pizzicato playing, while also ensuring long string life and high responsiveness.

Bassists using a low C extension value these strings for their reliability, while jazz bassists appreciate how well Spirocore works with amplified pickup systems. To further improve performance, Thomastik-Infeld addresses common string issues such as wolf notes and muting difficulties by winding the C and G strings in tungsten and silver.
