I love the tone of the Casady's low-impedance pickup: close to a P, but still its own thing. Don't like the ergonomics; you have to wear a wristband to keep the side binding from creasing your forearm, and even after putting on ultra-light tuners there's still neck dive.
The Lakland -- foremost, it's a different level of build quality. It's a fine instrument, not a production-line commodity.
Beyond that, you've got two Darkstars. I really appreciate that the bridge pickup has some space away from the bridge. It's roughly in a Music Man spot, so not too quacky or trebly. And the other pickup, slammed against the neck, isn't boomy or muddy. Together they sing. I'd describe the sound of the Darkstars in general as wide. They just sound wide.
It's a full-hollow with no center block like the Casady. It will feed back much more readily if I'm standing right in front of the 8x10 at healthy volume. Will report more on that after group practice this week.
The body of the bass is enormous. I am a 5'11", 145-lb stick, and it looks kinda funny hanging around my torso. But there's no neck dive, that's for sure.
Most of all, it may be only Lakland Hollowbody in the world with a 1.5" nut. I have a strong preference for the Jazz width, and I'm not aware of any 34-scale production hollow that offers one. So this particular axe checks all the boxes for my dream hollow.
