I have a bass I built a few years ago now and it has always had a buzz on the G string. It buzzes from 8th frett to the 15th frett. I have leveled and re-leveled and even re-fret it once to try and fix it. When I was re-fretting it I even re-leveled the finger board even though it did not look bad. Still there. I know the nut is not the issue since it only happens once it is fretted. Do you think the break angle at the bridge can cause this? I also tried a lot of neck relief and no neck relief, still a buzz. Has anyone ever had a problem like this before. Also do you think there is a way for it to be the string it self? Also to let you know I have leveled and re-leveled the neck in a neck jig set up to replcate the string load. I have also done it with the neck off the bass as just a normal fret level.
