Thanks for the comments chaps. The BB is the only one I've had from new, but somewhat perversely for such a great bass it's probably not worth me selling it, although I have to say I've no idea what the going rate (if indeed there is one) might be for a white (well, cream) BB, because I haven't seen one for sale for such a long time. I'm more inclined to sell the Jazz and the Goodfellow first, because I play them the least, and they'd be more significant in terms of cash return.
Over recent months, I can't put the Ray and the Overwater down, although they're nothing like each other: a proper Jeckyll and Hyde situation. The Overwater for when I'm feeling* talented and noodly, and then on the other hand nothing holds down a straight A like a Ray... I use em both for gigging and recording.
The Cort's a surprisingly good bass for the money, but that's strictly a bang-it-onto-EBay-for-£250-when-I-can-be-bothered sort of thing.
Hey, this is good - I'm actually thinking straighter about these basses than I have done for months. Blimey.
