John D’Addario's family has been shaping the music industry since the 1670s, when Donato D’Addario began crafting strings by hand. Following in this legacy, John's father pioneered synthetic substitutes post-World War II, revolutionizing string design. In 1974, John, along with his father John Sr. and brother Jim, introduced a new brand of strings, establishing a factory in Lynbrook, New York. NAMM captured a second interview with John, his son John (J3) and Jim to celebrate D’Addario’s anniversary in 2024, showcasing the enduring impact of their string company. Committed to music
