i did a few searches and came back empty,

could some one please tell ,e what would be the best way to create aa pedal that interupts or kills my signal when i push the button down and re engages it when i let it back up

thanks

Kill switch. Simple. Momentary switch that grounds out your signal.

probably want a cap in there to reduce popping too

hmmm... where would such a cap be of placement?

As long as you already have a pulldown resistor and a DC blocking capacitor on the input, I don't believe another capacitor would be necessary.

Why would you put a capacitor to prevent popping? Aren't capacitors the reason for pops in the first place?

I've built a mute switch for my buddy's Fetzer Valve and didn't need to add anything. I simply took the output of the volume pot and ran it to a DPDT that stomped between a line to the output jack and one to the chassis ground. The other half of the switch toggled a two color LED. No other protection was needed.

If you're using an LED, keep the electrical ground (battery or dc jack) separate from signal ground (sleeves), and you will be fine without any added components. If you're not using an LED, you have a passive box with no DC-related pops, and you're happy.

How can you keep them seperate? I found with mine if i didn't connect the jack grounds to the PCB ground I got a really crappy humming noise.
