    I recently purchased a set of medium Dunlop flatwounds (45-105). The G string has a case of fret buzz from the 3rd to the 6th frets. The rest of the bass is completely fine. My previous set of strings were Fender 9050Ls (same gauge G string) and there was no buzzing on that G string (relief and action were set similar to now).

    The relief is set to about 0.5mm and the action is quite high at around 3mm across all strings.

    What do I need to do to eliminate the buzz? I'd prefer not to add more relief (unless that's the only solution of course) as the other strings play perfectly. Could it be the nut or would the first fret also be buzzing in that case?

    Thanks in advance!

    In general the nut does not contribute to buzzing on fretted notes. I would use a credit card as a fret rocker and see if you have a high fret or two. It is also possible that a fret end has lifted a bit.

    Thanks for the tip. I'll have a look at the frets then.

    Is it also possible that more relief is required, or should 0.5mm be enough with a set of medium gauge strings?

    It is possible. Loosen the truss rod a but and see how it plays. But check the fets first. A loose fret is a pretty easy fix.

    Run your finger underneath the string and see if it has any divots, if the string got knocked that could cause it. Or it's possible you got a faulty string, happens a lot more with flats than rounds IME... actually I've never had a bad roundwound, but plenty of bad flatwounds.

    Suggest you loose all the string and leave it for 48 hours. Restring it from E ,A ,G , and D string the last. Don't do anything on neck relief and action. Play it for couple day then check/adjust your favorite neck relief and action . Once done, check on those buzzing fret on G string.

    0.5mm is plenty of relief, but it depends on how you are measuring it. If you are using the string as a straightedge, are you fretting at the first and last fret to measure the relief?

    Yes, I was using the string as a straightedge and fretting at the first and 17th fret.

    Good - you are measuring the right way. And that should be plenty of relief and string height, so there must be another problem. The possibilities are that there are some uneven frets or a bad string.

    Take the Dunlop G string off and put the Fender G string in its place - just the G string. See if the problem goes away. If it still buzzes the problem has to be the fret geometry - then look for uneven frets. If the problem goes away, check the relief with the Fender G string on - is it the same as with the Dunlop G string? That would tell us if there's a significant difference in string tension that is part of the equation

    Raise the action of the G string a tad. The middle gauges of the Fender 9050L's are 60 and 80 for the D and A strings; the Dunlops are 65 and 85. By any measure, that means more tension and possibly more relief. It seems to me that when you changed strings, the G string saddle dropped.

    I don't think this is a good idea. The string height is now 3mm across all strings according to the OP. That's plenty high and it's not causing a problem on the other strings.

    Thanks for the tips. I'll go through those steps when I have a moment and see if it gets rid of the problem.

    Turnaround is a real expert on this stuff. I would follow his advice.
