My questions relate to Fender guitars, but what has prompted me to ask them are my experiences with several recent fret leveling jobs I've done on Strats. Just because I have not had this experience on telecasters does not mean that it's a Strat thing. It's just luck of the draw. On a few fret jobs over the past couple years, and one I am working on now, I've run through all the expected steps. Upon completion. I check with a fret rocker, and everything appears dead level. If fall away was added, that checks out fine too. Neck goes back on the guitar, action is set to it's previous measurements, and the 5th and 6th strings buzz on every fret. Action on those strings is frequently 5/64th. Careful playing minimizes the buzz. No open string buzz. Add relief, very little change. Raise action high enough it will eventually go away, but sometimes it's ridiculously high. Any thoughts on what I may be doing or overlooking that is contributing to the problem?
