    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! :)

    Try changing the intonation screws from round head to oval head.

    It may sound like the buzz is coming from the bridge, but it could possibly be coming from one or more of the tuners. Grab the key of each tuner as you pluck the string and see if the buzz stops.

    I've tried to press onto these screws and it seems that this is the problem. So changing to oval ones would help?

    Well, I've been trying a few times more but it doesn't seem to help when pressing on screws. But I'm 100% sure that the buzzing is coming from bridge, on all strings on all frets.

    Springs on intonation screws.

    It may, the round head screw has a flat bottom on the head and can sit crooked on the plate. The oval head screw has a taper on the underside of the head and the spring will ensure it centers itself in the hole.

    You've probably already checked this but make sure your pickups aren't touching the string while you're depressing the strings on the last fret.

    The buzz is coming 100% from brigde. Knowing that it buzzes on last fret, it cant be anything on headstock right?

    Not to say that's what it is, but yes, it still can. Sympathetic frequency vibrations cause this.

    That said, if you think it's the bridge- probably worth focusing on that hardware - looking at the springs, screws, any loose metal, etc.

    If you suspect a spring on the bridge, remove it and gently stretch it a bit.

  14. I've run across loose grubs... If you have some beeswax under your bench, take out the grub, rake it on the beeswax to load it up and screw it back in...
     
  15. Loading grub threads with wax will also protect the threads a bit from corrosion so you don't have to do the soldering iron trick to try to loosen the grub way down the road...
