I just Purchased a Rickenbacker Bass I am not sure if it is a 4001 or 4003.Also I cannot find any serial number on it. the only numbers on it are on the jackplate one of them is marked J7 the other is marked 7554. It has made in the USA above the nut and it is like an emerald green color. can someone please help me out?
Thanks a lot
