I noticed a buzz when fretting the 1st string at the 5th fret last night. I moved up and down the neck on all the strings and this was the only place it happened. I have to fret it really hard exactly over the fret to some what stop it. No forgiveness at all. I did not have time to look into it with detail, but first glance it appeared the string is touching the 6th fret.
What would be a technique for checking such? Straight edge?
If the fret is high, can I file it?
Thanks in advance.
