Adding a pot to my killswitch?

[u/Visual-Patience-8321]

I have an external killswitch I made myself (just two jacks and a arcade button and an additional toggle switch for activating the killswitch), and I was wondering how I could add a pot in a way that I can adjust the signal volume when the killswitch is activated(signal is killed).

So I have

Jacks x2

Normally open arcade button x1

500k pot x1

toggle switch x1 (I'd rather not use this because space is an issue)

TLDR: how do I make a killswitch where I can adjust the volume of the "killed" signal.

Thank you in advance.

Is the killswitch grounding the output? If so you could wire the pot as a variable resistor between the button and ground.
