I've got a 2002 MIM P Bass that is in pristine condition. It looks almost new. I just swapped out the pickups and installed the vintage-style Fender bridge saddles. After I did so, I went about setting up the bass. I did a truss rod adjustment first, which I set to .015, and then I went to do the string height adjustment. I dropped the saddles VERY low and the strings are still too high. The E and G strings have the saddles dropped all the way so the screw hits the bridge plate and they're still to high. I'm thinking that I need to shim the neck or perhaps something else. What advice can you offer? (This was an issue before with the other saddles, although it didn't seem as prominent. Please help. This is a beautiful bass that I've put a lot of money into that I just have to get playing again!
