Grammer founded RG&G (Reid, Grammer & Gower) Company in 1965 with Clyde Reid and J.W. Gower. RG&G made the Grammer guitar from 1965 until 1968, when a fire consumed the factory in downtown Nashville. The company was then sold to Ampeg, and a new factory was erected down the street from the old one. The company was renamed Grammer Guitar, Inc. (GGI). GGI produced the Grammer guitar until 1970. His guitar was installed into the Country Music Hall of Fame in Nashville on March 1, 1969.
