In the 17-23rd fret range, the strings when played, are hitting the neck pickup/humbucker. Specifically, low E string hits the pickup starting at fret 18, A string at 20, D at 21, G at 20, B at 18, High e at 17. At these points, the string when pushed down are not hitting the fretboard for the most part, because they are hitting the humbucker. Is there anyway I can fix this? Also, open low e string buzzes, im thinking i might just need a higher nut, but I don't know, maybe it's related.
