Yeah, it would be - if that were true. While neck dive, IMO, is a subjective and personal thing, my '13 T-Bird is not high on my list of divers. And, I definitely own a few that are. On MY shoulder, it has a preference for hanging parallel with the floor - and won't go any further. But, if you wear it like lots of T-Bird players do; slung low, with the neck up at a steep angle? It's perfectly happy there...
And, mud? The original single pick up T-Birds may have been muddy-sounding - it was a Mudbucker pickup, after all; but the ones in my '13 are absolutely not muddy. They're just humbuckers. Very clean, loud humbuckers... I was amazed at how clean they sounded the first time I played it. Yeah, I was expecting mud, too - and didn't get it.
My only worry is that the new one won't be as well made as this one . Other than some fret sprout on 3-4 frets (and that's common for any bass/guitar that winds up out here in Vegas), my '13 is absolutely flawless. But, we'll see...

In the Netherlands, there is a man making his own Tbird inspired bass he calls the Lowlander.

Unfortunately no lefthanded option for this yet, but totally handmade, without neckdive and some other clever solutions, he might be interested to make a little lefty run. I informed for one, but that was (as of now) not yet within his possibilities.

Still a great way of turning his love for the Tbird into something like this.

I’d love to see what would happen if our very own Blablas turned his hand to T-bird creation... BlaBird anyone?

Not going to happen, I don't like the T-Bird shape.

I ordered an Ebony one this morning

Ordered the bright cherry Thunderbird today.
