I've noticed this for a while now, and I am just now asking about it. If I take my whammy bar out, it has a bunch of black stuff on it, which I think is abrasied metal from the bridge. And I also noticed that the part of my whammy bar that goes into the bridge is bent so it is pretty much like it has a dent. Even so, it seems harder for me to dive bomb and this situation than it was when I first started. I have the same amount of turns on it to keep it in place when I did way back. Is this abuse of the whammy bar, something I need to get checked, or something that just happens?
not sure about whether it's bad or not but my whammy bar has black stuff on when i take it out so it isn't just you
