Ha! Maybe you should put Locktite on your kidneys...I've got a collection of colours of Locktite as well and I take your point. Personally I can't see how a screw like that is going to fall out, but then I'm a bit of a stiff on stage.
I am not stiff on stage. In the least! Heh heh. I was reading on G&L before I happened to luck into mine. So that was the first thing In checked. It was, is, there. Nylon liner an all. It was loose, but intact. However...
One small niggle. To truly intonate my G correctly, the saddle ends up just behind the interior hole, where the screw meets the saddle. The lock screw still catches the saddle. But I can see it. I compromised, covering the hole with the saddle. It isn't a big deal, as my bass is a fretless, but I thought it might be interesting info here. I've looked at a ton of G&Ls. A recent convert that totally ignored the company til mine showed up. Now I love em. And the bridges I see have the G saddle farther forward than mine. I assume they are intonated correctly. But my G saddle, if I'm nitpicking, is a bit far back for perfect intonation.
