The quietener fits in your sound hole and the cutout fits around your feet board, you Still can hear the strings but no more will you be able to hear them from space
the smaller diameter is 84mm, I ordered the wrong size by accident
price of postage c. £1 is all I ask
Ok that is so totally far ahead of what I was saying and any way I could have expressed it but I think my point survived your expert scrutiny; the shield cannot usefully work without a connection to “ground” on the jack socket (whether or not that actually connects to the Earth) as that’s the only way you will shed troublesome EMF. This is what I was disagreeing with in @nancyjohnson post
I’m sorry but that just does not compute ... chords ... bass... it’s like “garlic ... bread?”
I'm joking of course, not in anyway resentful of other people’s talent, oh no.
Put them side by side and punch both at once. Economy of motion. 👌
make sure someone videos it, then put it on YouTube and when someone asks why, just say “I don’t like m....”
Surely the take-in of the emf causes a current in the shielding, you need to take that away. The energy doesn’t die if you leave it there, although it equally doesn’t die if you ship it to ground, but al least it’s not bothering you any more
