Well... I think a clearer analogy would be: I buy a new car, remove the hood, and discover that the engine has been crammed into the bay at an angle. And in that circumstance, I'd expect the dealer/manufacturer to at least humor my inquiry as to how a car rolled through QC with an engine hanging to one side. I'd be pretty cheesed off if I was told, "yeah, some of them just end up like that." Strictly speaking, it might not affect the car's functionality (at least initially), but it's hardly a confidence builder, is it?
Except that even this analogy is letting Rickenbacker off the hook. Because a car is infinitely more complex than a bass guitar, and it wouldn't take much for Rickenbacker or its dealer to make things right.
I say all of this as someone who's never owned a Ric, but has always admired their basses and the company's ability to ignore trends. There's just no excuse for shabby customer service, though.
