I was working on one of my "entry level" Strats today and quickly observed that the neck is NOT level with the body. The neck heal is fine, but the body pocket is deeper at the aft end than it is at the forward end by about .030". This gives the neck a very noticeable upward angle when bolted into place and that makes the strings really high on the upper frets (far more than can be adjusted for with saddle height adjustment). I have heard of this problem for a long time, but this is the first time that I have actually encountered it. I have been told that it is a simple fix by just putting some sort of shim in place a the low spot and then reinstall the neck. But to me, that means that the neck heel will only contact the guitar body at the shim and at the other end of the neck pocket, probably leaving a visible gap between the body and neck when viewed from the lower horn area. So, has anybody had this problem and fixed it satisfactorily with a shim, or is there more to it than that? I see that Stew Mac sells tapered wooden shims for this purpose, but they seem like an overkill for a "cheap" guitar". Advice?
