D'Addario XLB025W Bass guitar strings

Single Bass String for Custom Setups and Replacements

The D'Addario XLB025W is a single .025" nickel-plated steel bass guitar string built for long scale basses, sold individually so players can replace a worn string or build a fully customized set. As part of the XL Nickel Wound Bass Singles line, it shares the same round wound construction and distinctive bright tone with clear fundamentals that the XL series is known for across electric guitar and bass. Nickel-plated steel wrap delivers the punchy, articulate voice that works across rock, pop, funk, and gospel styles, while the .025" gauge sits naturally in the G-string position of a standard 4-string long scale bass. This single-string format is ideal for bassists who break one string and want an exact-match replacement without buying a full set, or for players experimenting with hybrid gauges and tunings.

Who It's For

The XLB025W is the right choice for bassists who need a single replacement string or want to build a custom gauge set on a long scale bass. It suits players running rock, pop, funk, blues, and gospel styles where the bright, articulate voice of nickel-plated steel round wound strings cuts through a mix. The .025" gauge works as the G-string on a standard 4-string bass, making it a natural pick for players who break that string frequently and want an exact-match replacement rather than a full set. It also fits bassists experimenting with drop tunings or hybrid sets who want to mix XL singles across different positions. Designed, engineered, and manufactured in the USA at D'Addario's New York facility, it carries the same build quality as the full XL bass string sets.
