Gibson started to move most Epiphone manufacturing to Japan in the late 1960s. The Rivoli line of basses disappeared then were resurrected in the 1970s as the Japanese made EA-230. Most models of this bass I have seen are in need of neck work. My was no different. The action got high past the 5th or 6th fret.
I sold mine recently after having been the owner for ~17 years.
I bought it at a Music Go Round when I was just starting to play bass at the Hill.
It served me well and was certainly a nice looking instrument.
