According to an article in Premier Guitar, Jim James uses D’Addario EXL115 sets to string up his electric guitars. Original article, dated June 2011, can be found here.

According to Premier Guitar 2021 interview with James, he uses D'Addario 9-42 EXL120 string set. This set is signficantly lighter than James' previous gauges. James describes the switch to lighter gauge as follows:

Opting for a slim neck is just one of the ways James has adapted his rig to his carpal tunnel issues. He's also switched to lighter string gauges. "It's helped a lot," he says. "I broke strings a lot in the old days. Before I had a guitar tech, I had to use .011s so I would make it through the show. I went down to .010s for a long time. This tour, we went down to .009s, and it's been incredible—the ease of playing. I went to extra-light gauge on the acoustic, too. I also try to limber up and do stretches. I hope I don't have to have surgery. And I have braces I wear when I sleep."
