D'Addario XLB075 Nickel Wound Bass String
The D'Addario XLB075 is a .075 gauge nickel-plated steel single string designed for long-scale electric bass guitars. Part of the manufacturer's established XL Nickel Wound series, it is utilised by musicians as a replacement string or as a component for assembling custom-gauge string sets.

Overview
The D'Addario XLB075 is a precision-engineered single string for bass guitar, featuring a .075 gauge thickness. As a member of the XL Nickel Wound family, it is constructed to meet the requirements of professional bassists seeking a balance between durability and tonal clarity. The string is sold individually, catering to players who do not require a full standard set or those who prefer to curate specific tensions for their instrument.
Construction and Materials
This string is manufactured using a round wound construction method. It features a high-carbon steel core wrapped in nickel-plated steel. This combination is industry-standard for achieving a smooth physical response under the fingers while maintaining the magnetic properties required for electric pickups. The long scale designation ensures compatibility with the majority of standard 34-inch scale length bass guitars.

Tonal Characteristics
The XLB075 is designed to deliver a bright and punchy sonic profile. The nickel plating provides a warmer character compared to pure stainless steel alternatives, while the round winding ensures solid sustain. This makes it a versatile choice for various genres, offering a smooth response across the frequency spectrum without becoming overly harsh in the high end.
Applications and Compatibility
As a .075 gauge string, it typically occupies a middle-register position in a standard four-string bass setup (often used as an A string) or serves as a specific custom gauge for alternate tunings. It is highly compatible with most standard bass bridges and tuning machines. Musicians often select this specific single string to replace broken components in an existing set or to experiment with string tension dynamics.
Market Position and Alternatives
Priced typically around £5, the XLB075 offers an affordable solution for maintenance. While D'Addario produces specialised strings for other instruments—such as the Zyex or Helicore series for violins—the XL series remains their flagship electric bass line. Alternatives in the market include offerings from Ernie Ball, such as the M-Steel or Slinky series, though D'Addario's nickel-plated steel is often preferred for its longevity and consistent performance.
