D'Addario XSB45130 Bass guitar strings

Coated 5-String Bass Strings Built for Long Life and Punchy Tone

The XSB45130 set delivers D'Addario's XS coating technology to 5-string bass players running long-scale instruments. Each string pairs a reformulated nickel-plated steel wrap wire with an ultra-thin XS film that sits roughly 10× thinner than a human hair, blocking sweat and grime before they reach the windings. Underneath, a NY High Carbon Steel hex core gives the wrap wire more surface area to grip, which translates into stable intonation and a familiar round-wound feel that doesn't read as coated under the fingers. Sized at .045"-.130" Regular Light, the set adds a low B-string to D'Addario's most popular bass gauge, making it a straightforward upgrade for players who want extended string life without sacrificing the bite of a fresh nickel set.

Who It's For

Bassists who gig regularly and dread the mid-tour string change will get the most out of this set, since the XS coating is engineered to hold up across months of fingerstyle and pick playing. The Regular Light .045"-.130" gauge suits long-scale 5-string basses across rock, pop, funk, worship, and session work, where a punchy low B and clear upper-register response both matter. Players moving up from uncoated XL nickel sets will notice the same round-wound attack with noticeably smoother slides and longer-lasting brightness. Studio players who record infrequently will also appreciate that the strings stay clean-sounding across long stretches between sessions, since the coating keeps contaminants out of the windings.
