Spirocore 1/2 Bass E String: Medium

The Spirocore 1/2 Bass E String: Medium is a premium replacement string for double bass players who want a clear, powerful low register with the fast response and durability that have made Spirocore a longstanding standard. Thomastik-Infeld's Spirocore Orchestra bass strings are built with a spiral core design that helps the string respond quickly while supporting a broad, vibrant sound. For bassists using a 1/2 size instrument, this medium-gauge E string offers a dependable option for serious practice, ensemble playing, and performance use.

As part of the Spirocore Orchestra line, the E string shares the same core construction and chrome-wound design used across the series. Thomastik lists the 1/2 size bass family with a vibrating string length of 110.0 cm and a usable range from 106.0 cm to 110.0 cm, helping players and shops match the string more confidently to the instrument. For players looking for a premium upright bass E string with strong projection, stable feel, and the flexibility to support both bowed and plucked playing, Spirocore remains one of the most established names in the category.
