Blackstone's bass on Al Green record

Anybody know what kind of bass(es) Adam Blackstone used on the new Al Green record?
I'm thinking it's one of his "modern" fivers dialed in for an old-school tone, but if it is, it's the most old-school sound I've ever heard out of a modern Ibanez or whatever he's using these days. Just curious.
He KILLS on that album BTW.
