This is what I call short circuit. It won't harm a pre-amp doing it by a
potentiometer, but I wonder if doing it fast, again and again by a
switch won't cause impulses, when the short circuit will be released
again? Perhaps I do error in reasoning and it's quite save.
Yes, it's entirely safe. At that stage you've got a few tens of
millivolts of signal at best, across about a 1k impedance source.
