There is no buzzing on any other frets around the fretboard.The truss rod is tight, it can go further but it is tight. The saddles can barely make it half way down before it buzzes like crazy again. Keep going until you find out which fret is too high. It means the 11th or 12th fret or even higher up might be a bit too high, so the string is hitting it. Lets say you try to play the 10th fret and just get a dead buzz. And if I drop the saddles even a little, the note doesn't even exist and you'll hear the same note (the note before it cuts out) over and over.^^^ hope that makes senseI checked for high frets by using a metal ruler and credit card and there does not seem to be any high frets.The action has to be too high (for my liking) for the buzzing not to be there. Some buzzing is caused because a fret up the fretboard is just too high.

Then position your point of sight exactly between both fingers looking vertically down on you fretboard. Put your left hands index finger on the first fret and your right hands index finger on the 12th fret. The note doesn't ring out, it gets cut out. Place all the strings back in the orrect groove on the nut careful not to tangle (if its a twelve string). There is a shim, but a thin shim.TL DR:- Frets 14 - 20 are fretting out and buzzing, no other frets are affected-Bridge saddles have to be high in order to remedy the buzzing, raising the action too high for my liking-NO high frets- What's wrong?I did search for higher fret buzzing but need some personal instructionAny thoughts? I just bought a bass and when setting it up I realized the bass has bad fret buzz on the higher frets.It starts around fret 14/15, and it's almost like a 'fretting out' sound.

Buzzing past 12th fret
