I recently bought a used MIJ Fender Strat. I noticed that the higher notes (especially on the top two strings) were dying out on the higher frets. There was also some buzzing coming from the frets, and the guitar had some tuning issues, going out of tune on the higher frets. I took the guitar to a technician to have it looked at. He said that the neck was bowed and that he could make an adjustment to the truss rod to straighten out the neck. He also made some adjustments to the bridge of the guitar. The bridge is a vintage style Callaham (set). I got the guitar back, and noticed that the buzzing is still there. I also noticed that the saddles on the bridge were set up at a slant, instead of following the curve of the fretboard. (I have been told that the low and high E strings should be set lower with the other strings a little higher) I'm getting fret buzz all over the place with this guitar, and I'm not sure what to do about it. Setting the action higher doesn't really seem to help. I use heavy strings (10s) Any suggestions as to what I should do? Thanks guys!
