I have a Private Stock 20th with the 3rd Gen tremolo. I am guessing a bit on how to properly set it up: string it, adjust intonation, they loosen the tuning a bit and tighten down the locking screws on the saddle. It makes sense to me that you want some string tension between the ball end and the saddle, even with a locking screw in the saddle. I don't know how critical that order is, but that is one question. Another question is an issue I observed: as I tighten down the saddle locking screw, something about a few of the saddles makes it so the whole saddle ends up backing up, leaving the head of the intonation screw sticking out of the rear of the trem plate, and making the intonation go off. So what to do about that?
