D’Addario, possibly the world’s most well-known guitar strings maker, can be traced back to the 16th century in a small Italian town of Salle. The D’Addario family was always in the string making business since 1680. Today, the company is still owned and managed by the D'Addario family. D’Addario designs and manufacturers a collection of music-related accessories, including guitar straps and accessories, such as tuners, capo, slides and picks.
