I originally had it in a Jackson Soloist and once I sold that guitar, I tried it very briefly in a PRS SE Custom 24 where it also sounded really good. I see no reason why it wouldn't work in a Jem just as I know the Holydiver will work. For what it's worth, I also had the Holydiver in my Jackson before the Miracle Man (preferred the Miracle Man, though both were good) and I currently have the Holydiver in my PRS. I'm not sure which I prefer in the PRS as I really liked them both. The only reason I kept the Holydiver and sold the Miracle Man was because the Holydiver is a bit more versatile. I now have three guitars and only two sets of Bare Knuckles so I really wish I'd kept the Miracle Man now :(
