I make my own shims using the same material that Fender used on vintage Fenders. Its the same thickness as my vintage shim that I bought for reference. I either copy the original shape (looser fit) or form fit it to the neck pocket just ahead of the screws. Its solid and sounds great; certainly better than the thin strip of cardboard it had...

I bought the red vulcanized fiber board in 2 different thicknesses in case the regular thin wasn't enough. I used the thinner one and its just fine on mine. I have it sit just in front of the screws. If the shim doesn't run even left to right, theres the danger of resting on one edge of the shim and not making contact evenly across the shim = less desirable. Sometimes the vintage ones have been roughed up the by the screws and the neck likely rides there instead. I have good even contact and its probably also why the Stew Mac ones sound and feel so right.

I bought the 3 pack as I was unsure which size to get. I used the .5 first & it worked perfectly. An expensive lesson I suppose.

Previously the bridge was so low it was almost touching the pickguard. I had some teflon tape wrapped around the bridge posts for the rattles. Got rid of the tape, reset everything, & the tremolo is dramatically better. Definitely worth it to me. No post rattles either with .012 flatwounds.

I've got a stewmac 0.5 shim that I'm gonna try on my jag, but I'm scared that when i take the neck off and then put it back on something about the setup will be "wrong" (besides bridge height) or I'll mess something else up. Also, do i need to unstring it or can i just loosen them?

^^^ You can loosen the strings (use a capo in the middle frets while doing this, so reassembling the guitar will be easier). Nothing can really go out of place, make sure you screw back the neck firmly but not over tighten the screws. Let us know how it went!
