Epiphone is an American musical instrument brand that traces its roots to a musical instrument manufacturing business founded in 1873 by Anastasios Stathopoulos in İzmir, Ottoman Empire, and moved to New York City in 1908. After taking over his father's business, Epaminondas Stathopoulos named the company "Epiphone" as a combination of his own nickname "Epi" and the suffix "-phone" in 1928, the same year it began making guitars. From the 1930s through to the early 1950s, Epiphone produced a range of both acoustic and (later) electrified archtop guitars that rivalled those produced by Gibson and were the instruments of choice of many professionals; a smaller range of flat-top guitars were also produced, some designations of which were later continued during the Gibson-owned era for the company.

Gibson Brands Inc. is an American manufacturer of guitars, other musical instruments, and professional audio equipment from Kalamazoo, Michigan, and now based in Nashville, Tennessee. The company was formerly known as Gibson Guitar Corporation and renamed Gibson Brands Inc. on June 11, 2013.
