There is a Rickenbacker 4000 for sale in Belgium. The ad says the bass is from 1992. Is this possible?? If it is an original Ric, than it's a steal, 850 euro.
While I have not established an end date, the 4000 petered out in the mid 1980s. The skunk stripe (shedua) was a feature from 1972ish to the end of the 4001 production in the early 1980s. This one is a set-neck 4000, sharing the same "chassis" as the set-neck 4001S of the period. I think '92 is out of the question, more likely late '70s, early '80s.
