D'Addario PB042 Guitar string

Phosphor Bronze Single String for Acoustic Guitar Replacement

The D'Addario PB042 is a single replacement acoustic guitar string designed to match the .042 gauge position in standard light and custom light string sets. Wound from phosphor bronze over a hex steel core, this string delivers the bright, warm tonal character that has defined D'Addario's Phosphor Bronze line for decades. When one string breaks or wears out before the rest of the set, replacing just that single string saves money and keeps the guitar playing consistently. The .042 gauge typically serves as the A string in most common acoustic string sets, making this the go-to replacement for players who want to maintain their preferred setup without changing the feel of the other strings.

Who This String Is For

This replacement string is the right choice for acoustic guitar players who need a .042 gauge string without buying a full new set. It suits players using light (.012-.053) or custom light (.011-.052) gauge sets who have broken or worn out their A string and want to maintain the same feel across all six strings. Singer-songwriters, gigging musicians, and hobbyists who play frequently will appreciate having a spare on hand for quick repairs. The phosphor bronze winding produces a balanced tone with clear highs and warm lows, working well for strumming, fingerpicking, and flatpicking styles across folk, rock, country, and blues genres.
