This course builds upon the foundational knowledge of the various Rickenbacker bass models that you acquired during your undergraduate studies.
Let’s begin our discussion by examining a unique topic: the 4002 bass. Who would like to volunteer to explain to the class what we’re looking at here? There were several unique features to the 4002, one (or more) pictured here - what were the features made the bass unique as compared to the 4001? Bonus: during what years was the 4002 made?
From @ronsvintageguitars:
Unique vs 4001 - use of RIC humbucker pickups with pickup placement shifted down - bridge PU just above bridge, "neck" pickup in middle between neck and bridge; ebony fretboard, dot markers, checkered body binding with black outer binding also on headstock. Model 4002 was produced from 1977 to 1984.
