Visually? The JO headstock signature is obvious and the dots on both are quite redonkulously ornate. But I’d say it’s more a feel. Maybe close to the way a pre cbs Fender feels compared to the later ones?
My Lakland experience? First I bought a newer 44-14 and flipped it immediately - totally not my thing. But I didn’t give up. Then I tried more than a few USA Glaubs. I bought a couple here on TB. Bought Tim Gibson’s Glaub. Bought a newer Coral one as well. Tim’s was a nice bass but the other newer one was....meh. Then I picked up the USA Glaub 01 and it felt....almost sublime. It had this supple feel that seduced me immediately. I won’t blather on, but I still can’t keep it out of my hands. I dug it so much that I traded a ‘69 refin J for a sub 50 USA JO and it has that same supple feel - just freaking “royal”.
When someone puts their own name and reputation on the line when building a product, it’s going to be a different product when they leave it behind; even if it “looks” the same. Even if those who carry on promise to uphold or go above and beyond the previous quality of build, it’s going to be different - hence the Fender metaphor.
I have a ‘79 MM and it “feels” different than the EBMMs. Not to mention it sounds a lot mellower. When Leo left, it was the same but it was different.
IMHO, when Dan left, the feel was different. Not bad - different. YMMV
