D'Addario BW045 Guitar string

80/20 Bronze Acoustic Guitar Single String — .045 Gauge

Wound in 80/20 Bronze — an alloy of 80% copper and 20% zinc — this single string from D'Addario's 80/20 Bronze Wound Singles line is designed as a replacement string or for building custom gauge sets for acoustic guitar. The uncoated wrap preserves the natural feel and acoustic resonance that has made 80/20 Bronze a go-to choice for recording sessions and traditionalists alike. At .045" (1.14 mm), it fits the 5th string position in standard light or medium acoustic string sets. D'Addario describes the tone as extra-bright mixed with deep and projecting bottom end — a character that has defined acoustic recording for decades.

Who It's For

Players who need a single replacement string at .045" gauge without buying a full set will find this the right choice — it covers the 5th string position in standard light or medium acoustic sets. It suits acoustic guitarists who prefer the bright, crisp, projecting character of 80/20 Bronze, a tone favored in studio recording and by traditionalists who value its vintage character. The single-string format also works well for players building custom gauge sets, mixing and matching individual strings to fine-tune tension and feel. Designed and manufactured in the USA at D'Addario's New York production facility, this string delivers the same quality as the full sets in the 80/20 Bronze line.
