resonator buzz - harmonic resonation
Hi - my son just bought one of those Gretsch Alligator resonator guitars and its pretty nice for an off the shelf new inexpensive one but the resonator makes a kind of buzzing sound around 490 Hz (e.g. open B string or fretted B on the G or D strings). Because when I hold down the resonator the buzz goes away. The other notes feel and sound fine.
I assume this is some sort of harmonic distortion b/w the resonator and this frequency someone know how this sort of thing can be fixed? Thanks Wayne |

Lots of possible causes. First thing I'd try is rotating the resonator to find a spot where it sits better on the flange in the body. You can rotate the biscuit to compensate. Once you find the sweet spot for the resonator cone to sit (that will probably be the cure), mark it on the cone and body (under the cover, where it won't be seen with the cover on).
You may need more break angle for more down pressure on the cone. That is a bigger deal to change. And of course, make sure all screws are snug.

StewMac has nicely written directions for setting up a resonator guitar on their website. Mine sounds considerably better after being adjusted and restrung. Might be worth going through just to rule out a setup problem.

follow up to Howard
Howard - so just to be clear. The resonator is held down only by string pressure through the bridge and the biscuit? So we need to unstring it, take the top plate off, rotate the resonator randomly, put it back together and try it out; and if that's not right, go at it again? Sorry this construction is new to me.
Thanks - Clintj I'll look at that for setup but the fact that its the same frequency on different strings suggests more what Howard suggests - but thanks. |

If he bought it new from a dealer, I'd take it back and have them fix it.

You may be able to rotate the cone by completely slackening off the strings, without removing the cover plate.
Then some trial and error. Sometimes only has to move a few degrees. Still a PITA but possibly do-able. Good Luck. |

Did I say this can be tedious? But you should only need to go through it once. There are a couple of resonator guitar forums where you can get more advice--probably better than mine.

Good advice above.
Also check to make sure the ball end of the strings aren't lightly touching the cover. My resonator bass suffers from that a little so a piece of leather between them was the solution. |
