Re: Intonation which ways which
Yeah, it's a slow, tedious process that requires patience. As Zerb said, you have to check everything when you make an adjustment to one.
When I made that last mods to LesStrat last year, one of the saddles when out of whack somehow. The bizarre thing was, I had to make some major adjustments to get it to where I could correct the problem. I didn't notice the saddle being out of place initially; I kept adjusting and adjusting and it didn't get better. But when I noticed it was out of whack, I put it back relatively even with the others and started over. Then I was able to fix it (and I was about ready to give up and sell it).
Again, patience is the key. Work slowly with minor adjustments, and double check the other strings as you get one correct. Then double check the one you're adjusting. Then...well, you get the picture.
