Yes, I’m familiar with Dan Daley’s Studio Sound interview and Jerden’s comments from Gearslutz/Gearspace. In addition to calling that Morin Marshall a ‘78 and ‘88, he’s also called it an ‘80 a few times.
Bryan Carlstrom wasn’t around for Facelift.
Dave Jerden has trouble recalling anything with certainty. The Randall was used according to him. Sometimes it’s cited as a head unit, other times it’s allegedly a combo. The “Marshall” he keeps referencing is a Super Lead, while you’re picturing a “JMP” aesthetic (and he explicitly said it wasn’t a “JMP”). Sometimes it’s claimed to be modded, other times it’s allegedly stock which he liked because it wasn’t overly gained up. Jerden has also confused Facelift and Dirt, stating the “Marshall” was for lows, the Randall for mids, and the Rockman for highs (which wasn’t used until Dirt).
All that said, Ronnie C and Cantrell have both stated time and again the Snorkler was used for leads, not a Morin. It’s the entire reason Jerry sought out Bogner gear afterward, unless you think both of them are completely wrong, he plugged into a Morin, and thought “Damn this Morin makes me want to go buy some gear from Bogner!”
