Re: Fret Buzz
Try toying around with a combination of truss rod adjustments and bridge adjustments.
Don't worry about using the truss rod, it is not brain surgery.
Take small steps at the time, give it a rest and see what it did.
If you feel insecure, write down everything you do and about how much you move things so you can turn it all back if you want too.
And, if the very unlikely event, that you screw things up is it not harder than to go to a trained tech and have it fixed again.
It is all screws meant to adjust the guitar with, they wont break unless you do something really stupid.
You will never learn to adjust guitars unless you start to toy around with it.
No technician in the world did know how to do it without starting tp toy with it without knowing, it is sort how we people learn new things.
If adjustments wont do it then there are the options that you neck has a bent/unevenness in it (pretty common that it starts at somewhere around the 14-15 fret, that the neck goes down from there so it is impossible to adjust it properly). Not always fixable but have a tach take a look.
It can also be that the frets are leveled badly. Easy to fix for a tech.
Also that one or two (or so) frets has loosen from the fretboard and are to high. Easy to fix yourself, have a close look at your frets. If you can see that some are not properly down in the fretboard, knock them down carefully with a little hammer and a piece of wood between the fret and the hammer (knock on the wood instead of strait on the fret).
Good luck and don't worry about toying around.
Very few things you can screw up cant be fixed again.
