how would i do this?

I want to make a killswitch pedal but don't want it to be too boring looking on my pedal board...

so how could i hook a LED into the circuit that would light up when the momentary switch is pressed?

Sorry about the noobishness of this post, i'm really bad when it comes to electronics and this is the first pedal "build" i've attempted...

You would need to find a momentary switch with normally off but many switches have both. Preferably double contacts. You want to ground the signal not open it to kill the guitar signal and then the other set of contacts you'd use for the LED.

thanks, but i just got advice from a friend saying 1k resistor :-0

should i just go with the 3k instead?
I'm no expert but I think 1k should be perfectly fine. That seems to be pretty standard. I looked at a TB loop schematic while I was making this because it's basially the same thing, and it recomended 3k-4.5k

1k seems to be what they use in a lot of pedals though.

If there is some weird noise (probably a buzz) when you kill the signal, it's a grounding problem. solder a wire from the top left thing on the switch to the ring of one of the jacks. I don't think you will need to do this, but it couldn't hurt.

The resistor is so you don't burn out your LED

here's your switch:

That might work but because you're opening and closing the signal path I think you will have noises. Instead I would just run a wire from the signal path to the switch and the other terminal of the switch to ground. Now when you hit the switch the signal path never opens it just grounds out. I have used the ground scheme on momentary kill switches on guitars and it works great.
