[quote="marton":2itrz7ll]Never regretted any 3 of them, although I never owned a vintage instrument, which I could have bought instead of my Prima. Do any of you DW owners own one or more nice vintage pieces? If so, do you combine them with your DW during a gig or do you prefer to play just the DW and if so, why?[/quote:2itrz7ll]
I have played vintage basses (J and P ). Count me among those who feel that the emperor is indeed naked. IMO they are collectible because they are old and therefore in limited supply. In my view, they are usually inferior to modern instruments in build quality; they have dead spots and frequently don't intonate well, and often have higher action as compared to a new, well-built bass. As far as the tone goes, if you dig old school thump, you can get there just as well with a new J or P, maybe some flats and a little attention to eq, as long as you don't listen with your eyes. Old school tone to me is about what's not there, and it's always possible to remove tones from a mix. Now I'll go done my asbestos suit

The best thing about a vintage bass, like any used bass, is that it holds its' value better than a new one.
As usual, IMO, IME, YMMV
