Sorry if we're only supposed to talk about sel-macs here, but this is about my archtop and nobody seems to know how to fix this. I get a buzz on the B string 3rd fret, G string 7th fret, and D string 12th fret. All D notes. The buzz seems to be coming from the tailpiece (check out the picture) It sound like a very high pitched squeel, and it is worst on the G string. I was thinking of maybe putting some tape around the string where it lays in the tailpiece, maybe to stop it from buzzing against the inside of the tailpiece. Any suggestions? Remember, it's only the D notes that seem to cause this sound. Thanks.
