D'Addario Strings manufactures strings for just about every instrument imaginable, and they've been doing it for over eight generations. Their strings are used on more stages by more professional players than any other, and their packaging is slick—D'Addario uses environmentally friendly string pouches, and intuitive colored ball ends for figuring out which string goes where when you're restringing your guitar. I've been playing guitar for 30 years, and after trying many, many strings on several different guitars, I often find myself coming back to D'Addario strings for their ability to hold tone, pitch, and playability.
80/20 Bronze, commonly referred to as brass, is the original acoustic string alloy selected by John D'Addario Sr. and John D'Angelico in the 1930s. 80/20 Bronze strings are popular for recording due to their crisp, bold, and projecting tone and appeal to many traditionalists for their historical significance.
