What can I do when my Legacy Trem Won't Stay in Tune?

[Craig]

I have a wierd problem on my newly acquired ('96) Legacy. The trem doesn't come back to pitch correctly
when you pull up on it. When you push down it's fine but when you pull up it's sharp. I replaced the nut and
the tuning machines and even added an extra spring to the trem. I called G&L tonight and spoke to someone
in the service department who was very cool and gave me a great clue. When I told him that I had my bridge
uninstalled and was looking at the studs and they seemed a little "sloppy" in their bushings, he told me that the
techs sometimes use Teflon tape to wrap the studs and take up the slop. Well I did that and also filed and
polished the worn spots smooth on the bridge plate knife edges, put it back together and voila!
