An Application For Rubber Grommets

If, like me, you’ve got cupboards full of small rubber grommets, I’m sure some days you sit around and try to think of a use for them. Maybe make an evening of it, open a bottle of wine, draw flow charts and diagrams in a vain attempt to just find some use for the things.

Well, I have it, the holy grail of surplus rubber grommet applications.

To stop sympathetic overtones on my mandolin.

Sorry, what’s that?  What the *** are you on about, Andrew?

Oh, I’d better explain a bit, then. With photos.

Sometimes the strings behind the bridge – the bits you don’t strum/pick – resonate in sympathy with what you are playing. unfortunately, since these bits aren’t tuned (or even tunable) the resulting tones are discordant and unpleasant. They are sympathetic overtones, or something like that.

Some players thread leather laces through the strings to damped the unwanted sounds, and some use small rubber grommets to stop the vibrations. So that’s what I’ve done. The grommets are slightly wider than the gap, so they get squashed slightly, but i don’t care.
