So I'm looking at purchasing a Rickenbacker from a guy here in town. I've yet to play the bass yet but of course, I'm going to play it before I buy it. So my question is this, is it a 4003 or 4001? it was made in november of 85 and is completely black. black headstock, black body, black pickguard. Normally, on all the Ricks I've played, the model number has been indicated on the truss rod cover. That is not the case on this bass. I can get pics of any other part of the bass if needed.
