Well, it's a difficult thing to comment on. I have a whole fleet of basses and only recently have added a 4003. My suggestion... keep it! Realize this instrument is likely not like anything you've played. It's hard to describe them really; they sound great but, they are certainly not "conventional" by any means. There's something to be said for a design that essentially has remained unchained for decades just like the Precision and the Jazz Bass. The difference? Well, Fender went a different route making less expensive versions of the same instrument. Nothing wrong with that, just different. Rickenbacker chose to stay the course, stay on the small side, more like a boutique manufacturer. I have to respect that, I think the same thing of Mesa Engineering... And yes, I play Mesa amps and cabs. I would advise that you just take it for what it is and don't try to make it otherwise. Here's a link to part of my story that involves Rickenbacker basses, maybe it will help you a bit...
