I've had a few Yamaha bassess, from a pointy headstock thing I forget the model number of but with a superskinny neck profile to a selection of broad basses - BB414 via a BB424, BB425 to a BB5000 that I imported from Japan. Fabulous things, I was particularly fond of the BB414 which I think, for the money, is hard to beat. Now all gone, mainly because a/ I find them too heavy and b/ I don't play long scale basses any more.
What I would like to try, but have yet to own, is the BB VIS - medium scale, slightly lighter body, single pickup broadbass model. Or, if the weight was right, maybe a BB VIIS, which is a PJ variant of the same medium scale, smaller body.
What I do still have, and it is arguably the best bass I have ever owned - certainly my favourite - is a Yamaha SB-35. Medium scale 'SG-shaped' double cutaway, single pickup. It is pretty straightforward, nothing complicated about it at all, but it is a joy to play and it just sings. That one is going into my coffin with me.
