Hello everybody. I have never been comfortable doing set-ups myself for the most part but I am sick of spending money on it and was thinking I may be able to diagnose and fix this problem without taking my bass to a shop. I have a Wal MKI that is having some very bad fretbuzz issues. The buzz is the worst on the 1st fret and slowly gets better as I go up the neck. Once I get up to the middle area of the neck the buzz is gone unless I dig in harder. The buzz is so bad on the 1st fret the note barely rings through. If I pluck my open strings hard enough I even get fretbuzz on the open strings. I tried raising the saddles a little but it didn't help. Is this a truss rod issue? If so what needs to be done to help fix the problem. Thanks everybody.
