here we go, i have covered this umpteen thousand times on ibanez forums....
its not the best trem in the world, it will eventually wear out on me, but for now its serving its purpose and you dont have the cool kid features like the edge,lo, and pro ones with an exposed knife window so you have to eyeball it, but the plate is definately parallel to the bottom of the baseplate, not the top and so like the edge and lo ones, you have a slight protuding angle of the top of the plate sticking up, not much but it is supposed to angle up like that
every single one of these has been setup with the top of things parallel like the edge pro and II ones in any shop i have taken a look at when tuned up to pitch, is it non stretched strings... or just misinformed inspection techs or whatever, dunno but I have found it to be perfectly stable and return to pretty close pitch everytime setting as close as possible to the bottom of it parallel to the body, not the top, that would return much worse, i should mention i swapped the stock springs for less stiffer ones off a fender and now I like the way it feels, it just needs some tlc, im afraid its been getting a bad rap because of bad setups honestly, is everyone now just in set it like the edge pro and II mode now???? dunno, im actually planning to attend Ibanez Dayz in houston where they are restring and setting up for free by ibanez techs, i plan to ask this very question what thier take is as I cant tell you how many topics contain this very subject on thier official forums they seem to ignore
YMMV as always but I spent a great deal of time dialing my guitar in and Im very happy with it
sorry this is a rant I have had for a while over on the ibanez forums, same thing with the whole LO TRS II rant, grrrr if people would just learn the facts, other than the crappy Korean II TRS trems, all the others are not that bad being Japanese made by Takeuchi, but I just get tired of hearing all TRS trems suck and swap for the OFR blah blah blah thing
not everyone can afford the best and you make do with what you got
ok rants off sorry
had to interject my 2 cents here
