Replacing a DPDT with a 3PDT LED switch in an MXR Dyna Comp. Can it be done?

I’ll start this by saying I am a dummy, not an electrician, and by no means a circuit board guru. I am an above average DIY’er with considerable soldering skils. Long time listener, first time caller….
I want to know if it is even possible to (and obviously how to) replace what I believe is a DPDT (6 pin) foot switch in an MXR Dyna Comp with a 3PDT with LED foot switch? I am just starting to dabble in repairing my own pedals as this is the first one that has failed and I ended up with a few of these switches that I would like to use. Any assistance would be appreciated.

Check the spacing. If you can get a DPDT worth of the the 3PDT to fit on the stock board then go for it.

However, the spacing looks off to me.
 
Correct, this won’t work as a direct replacement on the board. I was wondering if I could jumper from the board to the switch? And if so, what positions? Yeah, I know it’s more work than necessary, But it’s winter in Michigan and I have nothing better to do! Thanks!

If you have the space then sure.

Why would you?
Why not by a MXR replacement Footswitch, This already has an LED on the Pedal!
 
Genuine Dunlop brand ECB555 DPDT foot switch for use on the following Dunlop and MXR effect pedals. This switch in principle is used to solder to a plate (PCB) but make sure it is like that and for that reason you will have to read the details that come next: it is from Carling , it has a small hole in the shaft where the chrome-colored nuts go like the rivets on the board where the voltage information comes from (125V / 250V ...) and finally, the center pins are somewhat lopsided inward.

You guys have forgotten about the spirit of diy. There doesn’t need to be a good reason to do what we do.
Thank you Jimilee, your reply was dead on! If I wanted it done the OEM way, I wouldn’t waste my time and I’d send it to Dunlop. It doesn’t look that difficult. And it’s MY Pedal, I’ll Hack it if I want to! I like a challenge! Easy is for pussies. Some of these “Forum” cats are all the same. Ask for an “Answer”, get everyone’s longdick opinion trying to flex their prowess and knowledge. Thanks for everyone’s input, I’ll Do It Myself without a bunch of extraneous comments of how ridiculous it is. I’m not working on some Integrated quantum circuit, It’s a $90 pedal at best! I’m not fixing it because I’m poor! Sorry, you had to hear this on a reply to you Jimilee, you seem like a cool cat. Everyone else, keep up the great work in your mom’s basement. This will give y’all something to talk about at the supper table. FO

It can be done but it will look like Crap in that OEM case as the Footswitch Hole & LED will be non usable.
You stated can you use a 3pdt Footswitch so you can use the attached LED, now you are talking about True Bypassing also.
You stated that you are dummy & not an electrician so you were given a simple answer to get you a simple fix!
Don't come on a Forum and ask for Help if you don't like an honest answer to your simple fix you ask for !!!!!!! :censored:

Good luck with the extra holes in the enclosure. Nothing says DIY like shitty aesthetics!

Most welcome! Sometimes, I like to just answer the question without all the commentary.
