D'Addario NB020 Guitar string

Single Nickel Bronze String for Acoustic Guitar — Balanced Tone and Clarity

The NB020 is a single .020" gauge acoustic guitar string from the Nickel Bronze line, designed as a replacement string or for players building custom sets. It features a nickel-plated steel wrap wound onto D'Addario's exclusive high-carbon NY steel core, delivering the uniquely balanced tone and enhanced mid-range frequencies that define this series. Round wound construction reveals the full tonal spectrum of any acoustic guitar, allowing its natural voice to shine through. Unlike standard phosphor bronze strings, the nickel-plated wrap offers increased corrosion resistance for longer-lasting performance, even during heavy playing sessions. This string is made in the USA at the company's New York production facility.

Who It's For

The NB020 is the right choice for acoustic guitar players who need a replacement at the .020" gauge or who want to build a custom set tailored to their playing style. Its nickel-plated steel wrap and round wound construction make it well-suited for fingerstyle, flatpicking, and strumming across genres from folk and blues to acoustic rock.

Professional and intermediate players alike will appreciate the clarity, resonance, and projection that this string brings to any acoustic guitar. Part of the Nickel Bronze line, this string is trusted by artists including Julian Lage, Molly Tuttle, and Mike Dawes.
