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.
EJ26 strings are a D'Addario original hybrid gauge and a comfortable compromise for players who want the depth and projection of light gauge bottom strings, but slightly less tension on the high strings for easy bending.
Ernie's 2006 Earthwood 80-20 Bronze strings are made from 80% copper, 20% zinc wire wrapped around hex shaped tin plated steel core wire. They provide a crisp, ringing sound with pleasing overtones.
