My dad’s dobro got flipped upside down in an unlatched case. It had a terrible buzz, but it went away, so I never bothered to look at it. Yesterday it got dropped, and the buzz is way worse this time then last. The tailpiece seems to be rattling against the resonator, so I took it off, I didn’t see a problem. I took out the resonator also, and still didn’t see anything.
I started polishing the dobro, and I saw this. Could this be the issue? Or is it something else? What Is the recommended action to fix this?
I want to fix it myself, since I need the practice.
