    That is usually normal. The buzzing is like this

      The buzzing I'm getting is the same but a lot quieter.

        Hmm, makes me wonder if the panel is bad.

          Looks like this one's destined for the skip

            Just to make sure, is the buzzing skipping the occasional beat or changing frequency occasionally like it does in the video, or is it continuous?

                That might be normal buzzing from the Y or Z-sustain, it's usually very loud when the panel is cracked.

                  That's what I initially thought but it does sound exactly the same as the buzzing on the video you linked, just a lot quiter. Now I'm confused. . .
