Thomastik Spirocore Bass F# Extension String Solo F# 3/4 Size

This is a single Spirocore F# Extension 3/4-size bass string.

Hi-tech, top grade, spiral steel core strings. Spirocore strings are a further technical development of our K¸nstler Seil series and have a flexible spiral steel core. This core has greater elasticity than that of conventional strings, which means less inertia and a higher propensity to musical vibration.
