OK, I recently picked up a used Fernandes Tele copy...it's a really nice guitar. I played it for a while and it seemed fine and then one day I noticed that I was getting a severe buzz when I fretted the b and high e strings at the first fret. The buzz was so bad that the note just died when I fretted it. I figured it might need a new nut or a fret level. I sent the neck away to have a bone nut cut and installed and asked the tech to look at the frets...he put in the new nut and checked the frets and said they seemed OK (in fact it looked like the guitar had barely been played). He also mentioned that it was difficult to totally diagnose it without assembling the guitar and playing it (I just sent him the neck). I got the neck back, assembled the guitar and the buzz was still there. I figured it must be something else so I just left the guitar sitting on a stand for a few days. On a whim, I pick it up a few days later. To my surprise, it now plays OK when you fret the first fret. At this point I'm thinking that maybe the neck was backbowed or something and having it strung up for a few days made everything settle up OK. I take it to practice and it plays fine. Now, a few days later I pick it up and it's buzzing on the first fret again (but only really on the b & high e strings). When I say "buzz" I don't mean normal fret buzz, I mean the note sounds really bad and just dies. I'm puzzled. The neck seems very straight...very minimal relief at the 7th fret with the first and last frets depressed. What are some things I should look at? Unlevel first fret? If this was the case, wouldn't it always do it, and wouldn't it probably effect all the strings? Twisted/slightly backbowed neck? I can't help but notice that it effects the two strings that also have a string tree...could that be a factor? Any help will be greatly appreciated!
