My last 3 Jackson are Cort Indonesia and great other than one of the tuners was kind of loose. They are X series, not pros though. I've seen models made by Samick, too. Not sure if it's a model to model thing on where they get built. You may want to check out FGN (FujiGen's own brand). I feel like I've seen the mystic or mythic model in a 7 with a 1996, iirc and were in the same range as a bunch of Korean built similar models, although bolt on.
I've also been wanting to check out Jackson's new baritone range
Looking at their website on the back of one of the headstocks it says KWJ as the beginning of the serial, so possibly Korea World Jackson would be my guess. I know there is another Korean manufacturer that starts with a W, but can't think of it off the top of my head at the moment. Still going to guess it's world.
