Well as the title says I have a single buzzing note at eb on the g string at the heel of the neck and its driving me round the bend. I have tried the following - check the bridge alignment and. grooves. - raised the action considerably - changed the string - raised the height of the nut temp. To see if it might be buzzing behind the stopped note. All to no avail so I fear the board has worn a little because this note is one of my go to landing spots/reference points. Is there a way I could do something myself to the board in this spot because the only luthier I know in my area who has built a bass realised when fitting his bass's top that he had carved the integral bass bar on the wrong side of the bass. (Fail) so I am a bit apprehensive about sending my bass to him. Any input would be greatly appreciated.
