Mkgee jag & string type

So I know he uses a regular scale 60’s reissue jaguar that is tuned down to baritone tuning. His strings are obviously very thick and this all contributes to the foundation of his guitar tone.

I’m just wondering if anyone here knows if he uses flatwounds or regular roundwound strings? The tone sounds like flatwounds on hot jag pickups but hard to tell with his fx chain. The fashion show video he did looks like flatwounds but I can’t be sure. The tone is so warm but at times so bright.
