Hello! I'm having wierd problems with my bass. I've realised that I get buzz sound even if I fret on the last fret. But I've tried pressing down the strings at bridge and freting the last fret but the buzz persists. It's really wierd because strings don't hit anything as far as I can see. I get the same kind of buzz on all frets and even on open strings. But it's the same kind of sound as of the last fret. So the buzz must be coming from the bridge? If I pluck the string really hard it produces different kind of buzz. My bass has as far as I know perfect setup. Trustrod has spacing between fretted frets at 1st and 17th around 0.5mm spacing. String height is 2.4mm at E and A, and 2.1mm on string D and G on 17th fret. Frets are leveled, but not crowned perfetly, they have a but of flat surface, but that should not induce buzz. Anyone had the same problems? Thank you for any answers!
