I live in the country side of Japan. There are no real techs where I live, so they have to send it off to the Yamaha Factory for any major repairs. I asked them to do a fret level. Now my Japanese isn't that good, but I've brought 2 people now that understand English very well to explain. One a guitar player, but has never done or heard of a fret level. The first time, it took me about half an hour to explain what I wanted to do, so they sent off. I got it back and they removed some fret buzz that was noticeable, but here's the thing. No matter what, my e string buzzes on most frets when I have my action set a little over 2mm. Hence the reason for a fret level. Got it back, set it to about 2mm again and it still buzzes. They say they did the job, but I feel nothing has changed. This is my first fret level. So my question is that can they do a fret level and still have it buzz at exactly the same height that the E string was at before?
