I have a MIM Fender Jazz bass from the early 2000s that has sounded ridiculously good... until just last night. I noticed that now when I play the A string open there is a very strange acoustic noise coming from seemingly the whole guitar (though it’s louder at the body). It is best described as a metallic, high-pitched ringing noise. Seems to be the only string / note with this problem. The guitar itself is very resonant, if I tap a screwdriver to any of the screws on it I can hear the whole guitar make a gentle metallic ringing sound...
I have attempted to “dampen” various points where the string is transferring energy to the bass (IE tuners, but, bridge) but nothing seems to completely eliminate the problem. The bass has been well kept, apart from the few typical “dings” to a headstock that’s too far away for its own good...
Anybody have any experience with this problem? Or maybe some tips on how to further troubleshoot it?
