"Epi's first electric bass, the Rivoli, debuted in 1959, and it was the equivlent of Gibson's EB-2, a semi-hollowbody archtop modeled after the Gibson ES-335 and Epi Sheraton." (Walter Carter. Epiphone The Complete History, p.68.)

"The New York-based Epiphone company was bought by Gibson in 1957. One of the first so-called 'Gibson Epiphone' products was the Rivoli Bass of 1959, virtually identical to Gibson's EB-2. At first it was offered in natural or sunburst, later in cherry, and a two-pickup version was issued in 1970...The Rivoli proved especially popular with 1960s British bassists such as The Animals' Chas Chandler" (Tony Bacon and Barry Moorhouse, The Bass Book, p. 19).

"The U.S.-made Epiphone line from the '60s included the solidbody Newport and Embassy Deluxe basses, but the best known Epiphone 4-string of that era was the semi-hollow, short-scale (30 1/2") Rivoli. Only the shape of its headstock and the big "E" on the pickguard distinguished it from the Gibson EB-2." (Jim Roberts, American Basses, p.49).
