Resonator Guitar Buzzing Question

[Matt Haugen]

Hi all. I was gifted with a Gretsch Roots Series Alligator Resonator from my wonderful wife for Father's Day. I have been playing it pretty much daily and have been loving this guitar. Today I pulled it from the case and gave it a strum and it sounded as if it were electrified with a mild distortion. It seems more pronounced when playing an open chord. I hope I am explaining my issue correctly, to put it another way, it is like there is a vibration happening somewhere within the cone area, nothing close to a string bizz, but an actual rumbling. Pleace chime in if you are at all familiar with an issue like this. The guitar is brand new, I don't know if humidity could be to blame for this????

That should have read string buzz, I don't knw what a string bizz is.

First place I would check are the strings behind the bridge and the screws holding the cover down.

Matt I  don't know what you have there as I have never seen one of them .But if it is a Spider cone type of Resonator I my be able to help Bill............

Thanks Bill and Thomas. I will post some pictures tomorrow, but it is not a spider. I checked all of the screws today and nothing was loose, on the guitar at least.... I then decided to take the cover and tail piece off to inspect the inside. I am not familiar with the proper construction of these resonators, but I noticed something that I do not believe is correct in the construction. The inner well that the cone sits in/on is about 1/4 inch larger than the cone in all directions. The cone also just rests on a lip within the well instead of countersinking into a channel, which I thought is what I would find. This means that without string tension, the cone is free to move around the well. This guitar was (and still is) being mass produced in China, so I wasn't expecting to find a solid maple well or anything, but things just don't look right in there. Should the cone be snugly fitted into the well. Perhaps this extra space is to fine tune intonation?
