I have a Jackson DK2S, great guitar, but the trem bar has the slightest wobble even when tightened to the max. Not that it swings... when tightened it doesn't swing on its own, but when I pull up or push down on the bar there's a little movement that just annoys the crap out of me. It's a new guitar (bought it new) and is less than a year old. Anyone have/had this problem that can recommend a solution? Thanks.

I had the same problem on a DKMG and a DK2M.
What I did was, I snatched some clear nailpolish from the missus
and applied a few thin layers until the trem arm fitted nicely.
If you get a too thick layer just sand it down with some fine
grit paper, like 400 or more.
Nailpolish becomes pretty hard when it dries so it holds up
for quite some time, if you find anything better, just use that instead.
It seems like more or less all the modern Lic. Jackson Floyds have
this play in the trem arm.
All my OFR:s and Edge are much better and the old Schaller on
my Professional as well.
