I have a FR floating tremolo on my old Washburn MG-42 - full locking neck bolts although I'm told it's not an official FR but 3rd-party model.
I have no real experience using the whammy bar on any electric guitar and it always makes me nervous that something could go BANG... but particularly on a FR I understand one should be able to go 2-3 semitones in either direction (maybe more).
Can one be rough with the tremolo - is it something that can break or cause damage if you are not careful or is engineered so that you can really "go for it" without fear?
I'm asking generally but answers focusing on specific types of tremolo/guitar/whatever are welcome if appropriate.
