I see what you're saying here, and yes, in some ways you're absolutely right. A lot of the premium 'Super Fenders' by the likes of Sadowsky and Mike Lull, and even the German and newer Polish contenders can seem a little sterile for their comparatively huge price tags. Most don't even sound like a good example of a Fender. The answer continues to be, if you want a really good Fender sound, go out and play Fenders until you find a good one.
I've only played one Sadowsky I ever loved the sound of, and that was a Japanese 2 band Will Lee Signature. The rest sound bland and sterile to my ears. I tend to like the Mike Lull instruments better, but they still don't have 'that' Fender sound. For me, Bernie Goodfellow got it absolutely right with the Spitfire. It has the Jazz ergonomics and playability, but plays and sounds like a totally different kind of bass, much more premium and hand crafted and it doesn't try to sound like a Fender. It's truly a bass from the top tier of makers that can out punch a Stingray with it's metallic anvil-like attack, and has a sweet tone to boot.
I've been sorry to hear what's happened with G&L, but at the end of the day, they seemed to stop innovating in terms of the bass range some years ago. They certainly have their fans and I know @Mike Brooks really likes his newly acquired American L2000 CLF. Maybe they will re-emerge as a Fender sub-brand (particularly the excellent value Tribute models)?
