D’Addario, located in Farmingdale, Long Island, USA, is a maker of musical instrument strings, mostly guitar strings. The start-up is a family business with origins in Salle, Pescara, Italy. In 1905, two members of the D’Addario family, Rocco and Carmine, immigrated to the United States in an effort to develop the market in this country. After some historical events, Rocco returned to Italy and Carmine (later known as Charles) continued to stay in the United States to build the D’Addario brand. In 1974, J.

D’Addario & Company was established, becoming more and more perfect and growing as it is today. D’Addario strings are made according to the formula 92% Copper – 8% Tin, therefore the instrument produces genuine sound quality and strong reverberation in addition to the anti-oxidation action in the employed environment. D’Addario is a large and reputable corporation that not only manufactures its own branded musical instrument strings, but also manufactures guitar accessories for many other musical instrument groups, such as Planet Waves (specializing in guitar cables, amplifiers, and other accessories) strings, guitar strings, picks, and other accessories), Evans Drumheads (specialist in drums).
