D'Addario's XLB090 is a single replacement nickel-wound bass string engineered for long-scale instruments and delivered uncoated. The .090 gauge sits in the mid-range of typical bottom-end tunings, offering sufficient mass for defined fundamentals without excessive stiffness. Manufactured at D'Addario's New York facility, the string employs round-wound, nickel-plated steel construction to deliver the bright, articulate tone favoured by players seeking presence and clarity in the mix.
The nickel-plated steel wrapping provides enhanced corrosion resistance compared to traditional alloys, extending useable lifespan in humid conditions or high-perspiration setups. Round-wound geometry ensures consistent string geometry and reliable intonation across the fingerboard, whilst the proprietary core wire is drawn in-house to guarantee break strength and tuning stability. As a single string, it serves equally well as a targeted replacement or as a building block for custom sets tailored to specific playing demands.
