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!
