Overly-long explanation incoming!
I play bass, and Rickenbacker made a bass called the Model 4001. I've owned many over the years, none finer than my current bass, which was made in 1971. Here's a photo of a '71 4001
, mine looks exactly like this except it's got a Burgundy finish. Lemme tell you it plays like a dream! The "4001S" in my gamertag refers to a rarer model of bass that they produced in small numbers from 1962 to around 1990, though they've started making them again in the last year...
Aaaanyway, my service tag, "480" is a guitar that Rickenbacker made from around 1973-1984. I own this very early example from 1972
