Faulty 3PDT switch causing short to ground?

So, I’ve built 50+ pedals (vast majority PedalPCB) and while I’ve had some issues during the first few, with the help of a few of you here I’ve been able to solve. I’m happy to report that the last 35+ have been “issue free” and work great (thanks again for your help!!).

Well, I’m back again with another issue. Built my 5th & 6th War Scythe (I like to build in pairs) one works one doesn’t. On the one that doesn’t, led indicators all turn on and off with each of the three foot switches but I get no sound neither in active nor bypass. I’m also getting continuity between the positive and negative terminal on my input jack when I activate footswitch.

Ive ordered 3pdt footswitches from Amazon and Tayda and have never had an issue out of the 80+ I’ve used. I’m wondering if a faulty 3pdt footswitch can cause a short and not allow any sound in active or bypass but led’s still work.
Board is very clean, no visible bad connections, cleaned well with QD cleaner, reflowed all joints. I’m at a loss.

thanks in advance!

Hey did you ever find a fix for this? Having a similar issue
It was the 3pdt. Hasn’t been an issue since I switch to LMS for switches. Keep in mind, however, that there are other problems that can cause the issue that are not associated with the 3pdt.
