That photo makes for the biggest brightest "made in USA" I've ever seen on a Jackson Headstock....but that is indeed what it says.

Pretty sure those trems (590?) were standard USA production parts between the JT6 and Original Floyd Rose and were great trems. I've seen that colorized graphic only one other time and it was on an early 90's soloist...so I think 90-93 is a really good guess.

Yeah, that trem was on all of the 1990 to 1992 USAs that I've had over the years. Dinkys, Fusions, Rhoads, and Soloists. I've got the same trem on a 1990 USA Rhoads, with (what looks like) the same pickups too. I agree that 90-93 range is probably pretty accurate. I've seen the graphic once before, pretty sure it was a USA, but I can't remember what model it was...
