L'histoire derrière le son
1930
Working with luthier John D'Angelico, John D'Addario perfects the formula for the first iconic acoustic string set: a hexagonally shaped core coupled with an 80% copper and 20% tin wrap wire.
1970
John's son Jim invents a string prototype using a Phosphor Bronze wrap material. The set is immediately warmer sounding, but the true revelation is the strings last longer–sounding fresh weeks later.
1990-2000
D'Addario perfects EXP coating, which quadruples strings life without compromising the comfortable feel and legendary sound of D'Addario strings.
