The La Bella S660 double ball-end bass strings feature black nylon tape wound construction in a light 60-115 gauge. Designed for Steinberger and other headless basses that require double ball-end strings, these offer the warm, smooth tone of nylon tape winding with the convenience of the double ball-end format that headless instruments need.

Black nylon tape wound strings produce a deep, upright-like tone with virtually no finger noise. The smooth surface feels almost frictionless under your fingers, making long playing sessions comfortable. This combination of headless bass convenience and tape wound warmth is a specialty product that few manufacturers offer. If you play a Steinberger, Hohner, or other double ball-end bass and want that distinctive warm, woody tone, the S660 set gives you something genuinely different from standard roundwounds.
