Suggestions for trem arm slop in new Jackson Dinky?
Just got a new Jackson Dinky DK2S from an online dealer, with "JT580 LP" bridge. It seems like a decent guitar (and the Sustainiac is a blast- main reason I got it). But the linkage between the trem arm and the bridge is sloppy, no matter how hard I try to tighten the finger-nut which holds the bar into the bridge. I was hoping it would be as tight as the OFR on a 20+ year old guitar I have, but instead it's almost as sloppy as the screw-in bar in my Strat. No good for the Vai-type flutter effects, etc. This was a "floor" model and came with no manual or tools. I see an Allen screw head opposite the bar under the bridge plate (after taking off trem cavity cover on the back), but it is tight.
Any suggested modifications or upgrades to tighten this thing up?
I searched on here and elsewhere and didn't see any similar complaints, so maybe I should just send it back while I still can and try another?
Thanks in advance!
