Spirocore 1/2 Bass String Set: Medium

The Spirocore 1/2 Bass String Set: Medium is a premium upright bass string set for players who want strong projection, quick response, and dependable durability on a 1/2 size instrument. Johnson String describes Spirocore strings as built with a flexible multiwire spiral rope core that creates a longer period of musical vibration while significantly reducing inertia. That design helps the strings feel lively and responsive under both the bow and the hand, making this set a strong choice for advancing students, dedicated amateurs, and professional bassists working on smaller basses.

As part of the Thomastik-Infeld Spirocore Orchestra line, this medium-gauge set is designed to perform equally well for arco and pizzicato playing. Thomastik lists the matching 1/2 size medium set as model 3887,0 and notes a vibrating string length of 110.0 cm, with usability from 106.0 cm to 110.0 cm. For players seeking a high-performance double bass string set with a focused, flexible feel and a long-established reputation across orchestral, jazz, and crossover settings, Spirocore remains one of the most trusted names in bass strings.
