A kill switch is a short circuit, to 'stop' the audio signal.
I'm not fine with this solution, but the kids argue, that e.g. an
interruption does cause unwanted noise, especially for over drive
sounds. IMO even using opto-electronics won't solve the issue, because
the noise of the transistor overdrive effect still would be hearable,
while for a short circuit there is silence.
Has anybody an idea to solve this without a short circuit?
I'm really not a fan of short circuits. Note, it's not possible to do an
interrupt all the times behind the latest noise generator and even an
interrupt could cause noise itself, while a short circuit indeed is a
good way to cancel sound.
If you don't like short circuiting the mics, just switch the output jack
hot lead between ground and the volume pot(s).
Connecting the output to ground is the same as turning the volume down.
There is no need to short the mics...

Tom Morello gets real creative with his guirar, and uses this technique
alot. He also unplugs his guitar to make the pedals and amps make noise
(oscillate), and controls the noise with his wah pedal and by touching
the tip of the plug to the guitar bridge (which is grounded). Good
demonstration of how just cutting the signal lead can cause lots of
noise, while a short will be more or less silent :)

HI All
As a strat player noise is a real pain for me and worse around digital stuff
I record with.
I find for live work just use a noise gate pedal set to about 25db, or set
to just above any noise.
This should kill any noise in the system and open when you play.

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.

of my distortion pedal open and by carefully pressing two fingers

(Note to self: Remove socks and use toes next time, freeing up both hands!)
