D'Addario guitar strings

D'Addario is one of the world's most recognizable and respected names in musical instrument accessories, particularly for their guitar strings. The brand's history is rooted in a long family tradition of string making that dates back to the 17th century in Salle, Italy. However, the modern company as it is known today was founded in New York in the early 1970s.

D'Addario remains a family-owned and operated entity. While they have expanded their product line to include percussion (Evans), woodwinds (Rico), and various accessories, their core manufacturing remains centralized in Farmingdale, New York. They are noted for their high level of vertical integration, meaning they manufacture a vast majority of their components and packaging in-house to maintain strict quality standards.
