D'Addario Acoustic Guitar 80/20 Bronze Medium, .013 - .056, EJ12

D'Addario EJ12 80/12 Bronze Acoustic Guitar Strings, Medium, 13-56

D'Addario's heaviest 80/20 Bronze gauge, EJ12s offer heavier tension resulting in a bolder, more resonant acoustic tone with higher resistance for heavy strumming and flat-picking.

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, deep and projecting tone and appeal to many traditionalists and vintage enthusiasts for their historical significance.  All D'Addario acoustic strings are wound on a hexagonally shaped, high carbon steel core, resulting in long lasting, bright sounding tone with excellent intonation.

In the late 1930's, a young John D'Addario, Sr. met world famous luthier John D'Angelico (of course, at that time D'Angelico was not the household name amongst guitarists that it is today) and the two became close friends and business associates. These were the days before amplification, and D'Angelico, always looking for ways of getting more sound out of the guitar, encouraged D'Addario to experiment with new materials and methods. Together, they pioneered the basic set of acoustic guitar string core-to-wrap wire specifications that are now used the world over.

Their developments include the concept of using a smaller core-to-wrap wire ratio, the use of hexagon shaped core wires, the development of 80/20 bronze (technically known as brass), and the idea of giving guitarists the choice of light, medium, and heavy gauges. For decades D'Angelico and other leading luthiers purchased strings from the D'Addario family.

D'Addario's 80/20 bronze strings have the fullest fundamental low end and an extremely bright high end that tends to mellow more quickly than phosphor or 85-15 bronze alloys. 85-15 bronze alloys provide a more even tonal range.
