Anatomy of a D'Addario Phosphor Bronze Acoustic Guitar String

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.

Phosphor Bronze

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.

Round Wound

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

The Player's Choice

Ideal for the widest variety of guitars and musical styles, D'Addario acoustic strings are the choice of countless professionals around the world including Dave Matthews, Sheryl Crow, Keith Urban, Blake Shelton, Ryan Adams, and many more!
