when I first tried it for the low E string, I loosened the red one so much, that the whole saddle came out like I said. So when I put the saddle back, I pushed it away from the body and screwed in teh red screw at the 2nd hole (as you can see in the pic). Now this is the problem...cuz there's only 2 holes you can put that screw in, and since I need to push the saddle back even further, what can I do now that I've put the screw in the furthest hole?
edit: Nevermind! I got it! I didn't think the saddle would actually stay if I couldn't move the red screw closer to the saddle itself, but it works. Thank you Steve!
