I dont have one of those, but i know those bridges, so...
Like any bridge without loking nut, it may go out of tune if you use the bridge as a tremolo. Even a usa fender strat will go the same.
For exemple, an ltd m10, that is esp's most cheap model, comes with a fixed bridge. Personaly, i dont know if jackson shouldn't use fixed bridges in this cheap js's too. But if you use this dinky's bridge as fixed you wont have tunning problems, and also guives you the option to do [u]some[u] of the efects you can do with a floyd rose
, like playng a natural harmonic and use the bar to do cool heavy metal effects. However you probably will go out oof tune
, so i just recomend you do this when recording or at the end of a gig.
It's a cool guitar, i think you will like it!
