D'Addario XSPB034 Guitar string

Replacement XS Phosphor Bronze Single String for Acoustic Guitar

The D'Addario XSPB034 is a single .034" wound acoustic guitar string from the XS Phosphor Bronze line, designed as a replacement for a broken or worn string or for players who want to customize their set's gauge. Phosphor bronze — D'Addario's tried-and-true acoustic alloy — is wound round over a hexagonally shaped high-carbon steel core, delivering the warm, balanced tone that suits all musical genres from folk and blues to fingerstyle and rock. An ultra-thin XS coating is applied to the wrap wire and is engineered to dramatically increase string lifespan while preserving the natural feel and acoustic response of an uncoated string. Sold individually, this single lets a player replace just the .034" string on a standard 6-string acoustic without buying an entire new set, and offers enhanced break strength and tuning stability over standard 80/20 bronze strings.

Who It's For

This single is the right choice for acoustic guitar players who need a .034" replacement without buying a full set, or who want to build a custom gauge set mixing light and medium tensions. It fits any standard 6-string acoustic guitar and works equally well for strummers, fingerpickers, and flatpickers across folk, blues, country, rock, and worship styles. The XS coating makes it a practical pick for players who gig often or play daily, since the protective layer extends the time between string changes compared to bare phosphor bronze. Designed, engineered, and manufactured in D'Addario's New York production facility, it pairs naturally with the other gauges in the XS Phosphor Bronze series for a matched set.
