The La Bella S500L-B double ball-end bass strings are a five-string flatwound set in light 43-128 gauge, including a low B string. These are designed for headless five-string basses like extended-range Steinberger models and similar instruments that require double ball-end strings. Getting flatwound tone on a five-string headless bass is a rare combination, and La Bella delivers it here.

Flatwound construction gives these strings a smooth, warm tone with no finger noise, and the light gauge keeps the tension comfortable even with the added low B. The polished surface feels effortless for sliding, vibrato, and fast passages. If you play a headless five-string and want the classic flatwound sound for jazz, R&B, soul, or studio work, the S500L-B is one of the only sets on the market designed for your specific instrument. Specialty strings done right.
