I am quite impressed with it the ZR bridge in mine. From what everyone talks here, I had expected the ZR to have some trouble to keep tuning after a lot of crazy whammy bar action, but it is rock solid. I sometimes get the guitar to jam for a while and after 2/3 hours of jamming it is still in perfect tune. I also use it in full floating mode.
In fact, I expected a lot more grief for an Indonesian built guitar. Have not complaints as far as build quality goes. Only trouble, as I have mentioned before, are the pickups.
I also love the fact that if I have to adjust the spring tension, I only have to turn a knob instead of opening the cavity, getting a screwdriver and adjusting the screws to do it
