The La Bella S300 double ball-end bass strings are a five-string round wound set in 45-128 gauge, featuring a low B string for extended range. Designed for Steinberger and other headless five-string basses, these nickel-plated steel strings deliver a bright, punchy tone with the full frequency range you expect from quality roundwounds.

The 45-128 gauge provides balanced tension across all five strings, including a solid, clear low B that doesn't get muddy. Round wound construction gives you plenty of harmonics, attack, and versatility for styles from slap funk to aggressive rock to smooth jazz. Double ball-end five-string sets are a specialty product, and La Bella ensures headless bass players with extended range instruments don't have to compromise on string quality. If you need roundwounds for your five-string headless bass, the S300 delivers.
