Thomastik-Spirocore-Double-Bass-Strings-S42-JAZZ. Spiral steel core. Thomastik Product Code S42.

Spirocore Double Bass strings are a further technical development of the Kunstler 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. The sound is full and homogenous, balanced and voluminous. 

Gary's thoughts on Spirocore S42 bass strings:  "The S42 are the original classic spirocore, the string for that quintessential Ray Brown sound....Ray Brown not included.  They are developed for a bass with a longer string length...7/8 and up.  Using the longer string lenght on a shorter scaled bass gives us that nice easier to play growly string.  As bassists we have been doing this for years not even knowing that the string were developed for a bigger bass!"
