Re: Whammy Bar To low help
Unfortunately, yes. If you remove the bar and look at the end of it you'll see two white nylon bushings. After a short time of use, these wear down and the arm becomes sloppy. You can either buy new bushings (ridiculously expensive considering what they actually are and how often they need replacing), or you can do what many of us do and buy yourself some plumbers tape (PTFE).
I have always been angry with Ibanez for making the bushings so expensive. There is absolutely no reason why they should cost so much and to be quite honest they really need to look into a better solution. The Edge trem is 21 years old and to rely for more than two decades on such an obviously flawed piece of hardware is nothing short of ridiculous.
Regarding the plumbers tape, read on.
Remove the bar, remove the bushings, and cut yourself a couple of inches of tape. Wrap the tape tightly around the area where the bushings live, then replace the bushings. You should now find that the bar feels good and stays in place for a while, but you'll soon be repeating this procedure because the tape also wears out.
