D'Addario Silk & Steel Acoustic Strings EJ35, 12-String, 35-12

Your strings matter. D'Addario's Phosphor Bronze acoustic guitar strings are engineered to serve as the critical link between you and your guitar. Our most popular acoustic guitar strings, EJ's are precision wound with corrosion resistant Phosphor Bronze onto a carefully drawn, hexagonally shaped, high carbon steel core. The result is long lasting, bright sounding tone with excellent intonation.

Three components of a D'Addario guitar string work together to create your desired tone: Hex-core, outer wrap wire, and ball-end. It all starts with the core. D'Addario pioneered the use of the Hex Core, and as the name suggests, it is a six-sided high carbon steel core-wire. Each side "bites" into the wire used for the outer winding, creating a tight and consistent bond that keeps the string in tune from end to end. The final component is a D'Addario exclusive: color-coded ball-ends that secure the string in place at the guitar's bridge, allowing for easy string identification and a major reduction in wasteful packaging.

92% copper and 8% tin with phosphorous, introduced to string making by D'Addario in 1974 as the first "extended life" strings. Phosphor Bronze is synonymous with warm, bright, and well balanced acoustic tone.

The most popular and universal construction, Round Wound strings deliver the traditional textured feel most players are familiar and comfortable with.
