What happened to Paul McCartney's Rickenbacker bass?

He still has it! However, it hasn’t been sighted much since the Wings era so it's probably gathering dust under his bed. McCartney famously painted his 4001 to fit in with the psychedelic visuals of The Beatles’ Magical Mystery Tour film. A couple of years later he decided they had had enough of psychedelia so sent it back to Rickenbacker for them to take the finish back to the natural wood.
