D'Angelico was already known for the zinc coated steel strings back in 1938. Come the 1960s, the manufacturing plant was shut down so all was lost in terms of benchmark; nobody quite manufactured strings that sounded good. This was revived recently seeing a collaboration with D'Addario. So it's a D'Angelico design being paired up with D'Addario's coating technology. Hope these will make it here, of course.
