Not sure about the thread title, but basically whenever I let go of my whammy bar, it drops back down and swings around a lot. On live shows, I see players with a whammy bar let go of it and it just stays in place. How can I do this?
Be a man and tighten it down better.
You can get medicine for that. Seriously there are cures for your erectile disfunction.
It depends on style whammy bar/bridge you have.
if you have a non-floyd rose trem, just screw it in further. no sexual pun intended there. if its a FR or an edge, there's a small allen screw thing under where the bar goes, lif the FR and tighten it.
just fit a rubber gromet on your bar or in the nut that it goes in to.
Push the whammy bar down and hold it, and look under the bridge. You'll see where you can tighten it.
wrap PTFE tape (Teflon tape) a.k.a. the white tape around a blue holder around your whammy bar, then screw it in.
