| Does the buzz disappear if you raise the action on the A-string? If so, how much higher do you have to raise the action of the A to eliminate the buzz? Can you hear the buzz through the amp, or only when unplugged?
I've also heard that the Sadowsky guide has you set the action very low. If this is true, it is possible that you may not be able to get such low action, as many factory basses' frets are not always as level as they should be. |
