From 1958 to 1970, Epiphone guitars were produced in Gibson's Kalamazoo, MI factory, and shared the similar design, materials and electronics as their Gibson counterparts. The Riviera, Sheraton, Rivoli and Newport models shared similarities with the Gibson ES-335, EB-2 and EB-0 models, respectively. In 1970, Epiphone production ceased in the Kalamazoo plants and Epiphones were made at the Matsumoku factory in Japan. Later Epiphones were constructed under contract with Samick in Korea. These early Epiphones are generally thought to be of good quality. Since 2002, almost all Epiphones have been made in the 'Gibson' Qingdao plant in China.
