I’ve got a Southern Jumbo and have always understood that it’s pretty much a J45, but just a bit more fancy looking. Then there’s the Sheryl Crow SJ……. At one point I considered one of those. Lets face it, having one of those is about as close as I’ll ever get to touching something that looks like something that touched Sheryl Crow’s lap. Anyway, I don’t need to be touching or sniffing something like that late at night ( there’s already more than enough Emmylou pictures floating around this forum)……. As it turned-out, I bought Rosewood SJ.
