The bass in question: MIA Fender Jazz Deluxe. The problem: The E-string gives off a strange buzzing sound. When I pluck my E-string on any fret, I get a very strange buzzing sound. It is not fret buzz, but rather it sppears that the frequency of the notes is making something else buzz. It sounds like an echo-ey, reverb sound. I can't really explain it but it bothers me to the point where I don't want to play. Here is what I've done so far: Strung the string through bridge as well as body Changed the E-string Removed pickguard and all electronics Removed all knobs Held down the bridge while plucking Removed the batteries Adjusted the action higher Held down each pickup while plucking the string Elbowed the bass a few times Tightened the neck and bridge Placed a piece of paper between the string and the frets, and plucked it at the 12th fret. Removed all strings except the E and plucked it. --- None of these things seem to fix it. It is not fret buzz and I have tried 3 different E strings. I'm really lost; any ideas?
