“Nickel Bronze brought new life back into my Collings OM2H. The tone is balanced, organic and punchy. These are the strings to beat.”


“Nickel Bronze brings out the old charm in my 57' j45. They have life but without the harsh brightness of brand new strings.”


“You know how guitar strings sound best when they’re just about to break? Well these sound like that fresh out of the bag! Dig it.”

— JIMMY VIVINO / Conan O’Brien —

“Nickel Bronze strings have that warmth I used to have to wait a week or two for.”


“The NB acoustic strings are equivalent to the NYXL electric strings in ultimate quality. They’re warm, vibrant, and bring out the personality in each of my acoustics.”

— SEAN WATKINS / Nickel Creek —

— Darryl W. —

“These strings made my guitar come alive again.”

— Eric A. —

— Randal S. —

“I like the crisp tone and volume in comparison to my old set. They seem to really wake up this mandolin.”

— Bill B. —

“These strings really bring out the tone of my mandolin. I like the depth of sound I’m getting and I like the feel of them too. They’re more stable than other sets I’ve used.”

Acoustic Properties
Tone Revealed
Nickel Bronze features nickel-plated phosphor bronze wire wrapped around a high carbon NY Steel core. This unique combination preserves the familiar low end depth and warmth of phosphor bronze, while boosting mid and high range frequencies to deliver greater clarity, projection, and harmonically rich overtones.
Enhanced Pitch Stability
Nickel Bronze strings are engineered with NY Steel, D’Addario’s proprietary high-carbon steel wire that increases pitch stability, break strength, and overall string life, so you can spend less time tuning and more time revealing the unique sound of your instrument.
