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.
