D'Addario BW027 Guitar string

80/20 Bronze Wound Acoustic Guitar Single String — .027" Gauge

The D'Addario BW027 is a single replacement string for acoustic guitar, sold individually in .027" gauge. It belongs to the 80/20 Bronze Wound Singles line, an alloy co-created by John D'Addario Sr. and John D'Angelico in the 1930s that remains popular for its bright, crisp, and projecting tone. This string works as a direct replacement for a broken or worn .027" on any standard acoustic guitar, or as a building block for players who want to assemble a custom gauge set. The round wound construction with a nickel-plated steel wrap delivers the extra-bright top end and deep bottom response that recording studios and traditionalists favor. All D'Addario strings are designed, engineered, and manufactured in the USA at the company's New York production facility.

Who Is This String For

This single string is the right choice for acoustic guitar players who need a .027" replacement without buying a full set. It suits players who prefer the bright, crisp character of 80/20 Bronze over the warmer sound of phosphor bronze, and those who want to customize their string gauges by mixing individual strings from different sets. The .027" gauge is a common mid-range thickness that fits most standard acoustic guitar string sets, making it an ideal spare to keep in a gig bag. It's also well suited for recording sessions where the extra-bright top end and projecting bottom response of 80/20 Bronze are valued by engineers and players alike.
