D'Addario LE042PB Guitar string

Phosphor Bronze Single String for Acoustic Guitar

The LE042PB is a single replacement string for acoustic guitar, wound in phosphor bronze at a .042" gauge. It belongs to D'Addario's Loop End Singles line, which lets players replace one broken string without buying a full set, or mix and match gauges to build a custom set tailored to their playing style. The string uses a hexagonally shaped high-carbon steel core precision-wound with corrosion-resistant phosphor bronze, producing the bright, warm tone and long life that this alloy has been known for since D'Addario introduced it to string making in 1974. The loop-end design fits acoustic guitars equipped with loop-end bridge pins rather than the more common ball-end design.

Who It's For

This single string is the right choice for acoustic guitar players who need a replacement at the .042" gauge — typically the D string on a standard light or medium set — without buying a full pack. It suits players of folk, bluegrass, country, and singer-songwriter styles who prefer the warm, balanced tone of phosphor bronze over brighter 80/20 bronze alternatives. The loop-end construction makes it a practical option for vintage or boutique acoustic guitars, mandolins, and other instruments that use loop-end bridge pins rather than ball ends. Both beginners who break an occasional string and experienced players who like to customize their string gauges will find this format convenient and cost-effective.
