D'Addario XLB120 Nickel Wound Bass Guitar Single String Long Scale (.120)

The D'Addario XLB120 is a single long-scale bass string engineered for players building custom sets or replacing worn fundamentals. Nickel-plated steel construction delivers the bright, articulate tone that defines modern bass rigs, with enough output and presence to cut through dense mixes. D'Addario manufactures these strings at their New York facility, applying decades of experience in round-wound string geometry and alloy composition.

At 0.120 inches gauge, this tapered long-scale string suits 4– and 5–string basses requiring heavier bottom-end foundation. Round-wound construction with nickel-plated steel wrap provides increased sustain, bite, and corrosion resistance compared to legacy materials. The proprietary core wire is drawn in-house to ensure consistent break strength and intonation across the set. A single uncoated string allows players to source specific gauges without committing to full sets, ideal for custom tunings or replacement scenarios.
