My take on this is that, in the grand scheme of things, I think that Fender has done a very decent job in offering lefty instrument. (Don't forget that Fender started offering lefty basses and guitars almost since day one, which is a pretty significant fact.) Fender offers a lefty version of almost every
type of instruments they produce - just because they have 1-million variations of the same 10 models, it wouldn't make sense for them to produce lefty versions of all those variations. My biggest beef with Fender is (was) that they stopped producing lefty Jazz basses in 1982, but that was corrected in 2008 (or '07). Sure, I'd love to see a maple-neck lefty Jazz, but personally I don't think it's such a big deal. And my other only beef is that they've never produced a 5-string lefty. But in my case, it doesn't matter because I know their 5-strings tend to have a really beefy neck, and I probably wouldn't own one anyway. Thankfully we have Carvin, EB/MM and G&L for those mid-price American 5-string needs.
And about the American vintage reissue stuff, they sure look good, but technically they are an inferior product than the current American Standard series. Weak truss rods, no graphite rods (which to me help keep those pencil-thin Jazz-bass necks straight for years to come), no shielding, heavy tuning keys. . . I love a well-played, relic'd vintage Fender that is 30+ years old because of the mojo and the dry wood, but I don't see the appeal of getting a brand-new vintage-correct instrument. IMHO. (Some say that graphite rods affect the sound and doesn't result in a vintage-correct sound. . . Really? Only you and your cat cares. . .
)
Also, Fender not offering the vintage stuff shouldn't be a concern when you can build yourself a nicer vintage-spec Fender-type bass using licensed parts from Warmoth, US Custom Guitar and others, for maybe even less than what Fender would charge. It just takes a little more work, and you won't have that Fender decal on the headstock, but it's very doable with just a bit of planning and patience.
And of course I also agree with what Rod said: support those companies who go the extra mile to cater to lefties, instead of begging those companies who won't. And that, children, is the moral of this thread.
