Thunderpuss won't work. It just hums.

Ok, this is my 3rd build and I don't know why this won't work.  When I plug it in all it does is hum.  Even if it is bypassed.  Still a hum.  It gets louder when you engage it though.  I tried to take pics and they are super blurry. I'll try again but any ideas.  I've checked my joints and even values like I read on another post.  I even removed the 3pdt switch and it still hummed.  You can very very faintly hear a little guitar when you crank it up but barely through the hum. Please help.

First guess would be a grounding issue.   Are you using plastic or metal jacks? If plastic, make sure both are grounded, and make sure your entire circuit is grounded properly.

I thought that too but couldn't find anything.  I am using metal jacks so just the input is grounded. I'll check grounding again though.
