D'Addario EJ12 80/20 Light Gauge 13-56 Bronze Acoustic Guitar Strings

D’Addario EJ12 80/20 Bronze Light Gauge 13-56 strings are designed to make your acoustic guitar leap out of the mix with brilliant clarity and powerful projection. Combining a high carbon steel core with an 80/20 bronze wrap, this classic set delivers a bold, sparkling top end with plenty of depth in the lows, ideal for players who want maximum volume and a punchy, articulate tone.

Originally developed in the 1930s by John D’Addario Sr. and master luthier John D’Angelico, 80/20 bronze has become a go-to choice for players who love a bright, lively acoustic sound. The EJ12 set pairs that timeless alloy with a 13-56 light gauge, giving you extra tension and resistance under the fingers for a more authoritative feel, stronger projection and a tone that stays clear and defined, even when you dig in.

Whether you are a flatpicker chasing a cutting lead tone, a strummer who needs chords to shimmer on stage, or a songwriter looking for a vibrant, responsive feel under the hands, EJ12s give your acoustic a distinctive voice that commands attention. The uncoated construction keeps the playing feel direct and natural, letting every nuance of your technique come through.

Bright, Sparkling Acoustic Tone

80/20 bronze is D’Addario’s brightest acoustic string alloy, delivering a crisp, trebly top end with rich harmonics. On the guitar this translates to chords that shimmer, arpeggios that ring with detail and single-note lines that cut through a mix with ease, making EJ12s ideal for live performance and recording.

Powerful Projection and Volume

The 13-56 light gauge provides higher tension and resistance, helping your guitar project more strongly. You get a firm, confident feel under the picking hand and a sound that stays full and present, even when playing hard, so your acoustic can hold its own in louder ensembles.

Classic 80/20 Bronze Construction

Built with a high carbon steel core and 80/20 bronze wrap wire, EJ12 strings offer a tight, responsive feel with excellent tuning stability. The combination of robust core and bright wrap material gives you both depth and clarity, with a focused low end supporting that signature sparkling top.

Natural, Uncoated Feel

These strings are uncoated, giving you a direct, traditional playing experience with no additional layers between your fingers and the metal. The result is an immediate response, a familiar tactile feel and a tone that is open and unfiltered, ideal for players who prefer a classic acoustic string.
