His signature Jackson has them stock. And he did play their prototype models with the same pickups so the answer is yes. But it is not the "Rhoads" tone many people think of, as the model was not released until after his death, so he didn't get to use them much at all. But yes, he did use them very briefly.
I'm pretty sure his live tone on Tribute is a Super D loud and proud through a cranked Marshall and I believe an MXR distortion pedal.
Where did you get this info?
His LP had stock T-tops in it. The Polka dot V had Dimarzio Super D and PAF in it. The Concorde and Rhoads V's both had Jazz and Distortions in them. What guitar did he ever use that had JB's prototype or otherwise in them?
Where are YOU hearing that his concorde and rhoads v have a distortion in them. Everywhere I'm reading says it's a TB-4 JB and has been.
It's widely known that the Jackson's had Duncan Distortion/ Jazz pickups in them- this was really before they were production models.
Once they became production models, the bridge became a JB, though since Jackson's were all custom at the time you could get anything you wanted
*edit. OKAY I found it. His SECOND Jackson prototype Concorde (black and gold with elongated upper horn and fixed tailpiece) had the JB in it, the first one (white pinstriped sharper V) had the Distortion. The JB was his final say and that's why the Jackon Rhoads signatures have them to this day.
What guitars did he use to play certain songs live?:

Wait so now we're not sure of the neck pickup either? Ok I give up. My sources were Jackson themselves and a few other blogs about the Concordes like this one,

Even the Custom Relic of the Concorde that Jackson presented to Rhoad's family featured the JB in the bridge and that costs upwards of 9 grand. I've found some other things saying that prototypes had "Habanero" pickups in them? Most of the places just say "seymour duncan pickups" not even specifying, but yes I've found a few that say the distortion too. It's not too hard to imagine he used both but this is pretty hard to nail all things considering.
