someone said: Securing the "Floating" Bridge
Tools/Parts Needed:
Electrical tape
Scissors
Again, if you want more tuning stability one of the easiest things that you can do is to secure the rocking bridge. It's simple and doesn't cost more that $3.00. First remove the bridge and notice that the posts on the bridge are much smaller than the holes on the bridge plate. First, take the electrical tape and cut a peice about 8" long. Put the tape on the post to see how much to cut off, I'm talking about the width of the tape now, just cut the whole 8 inches the same length as the posts. Now wrap the electrical tape around the posts. Check to see if it will go into the bridge plate, if it doesn't, unwrap a little of the tape and cut it off. Try it again and again until you can slide the bridge in and out vertically, but you can't move it back and forth horizontally.
Yes, the floating bridge can be quite a pain. Very much like a strat bridge if you have it set up in a "float". (can tremelo up and down)
I usually have the best luck keeping these bridges in tune by pulling the bridge as far back as possible. (towards the tailpiece where the strings wrap around)
Here's a nice excerpt from an article that was about the jaguar bridge at this url: http://www.jag-stang.com/JaguarHtml/jaguarBridge.php
You could also put tape around the bridge posts to help minimize the range of movement the bridge has as described in the first part of this article: http://www.jag-stang.com/techTips.htm
