I took everything out of the enclosure and I get the same thing.  It has to be a short somewhere right?

It's also possible that it's a cold or loose solder joint due to the stress induced when you fix them to the enclosure.

I'd check the delay pot connection and the associate parts. Using an audio probe you should be able to listen to the input of the PT2399 and see if signal is hitting that point, and then if it is, you can check the output and trace to the Mix area.

I'm with Jon. Sounds like a short on the back of the pots or a cold solder. If you don't isolate the back of the pots (double side tape or dust seals) you WILL have trouble.

I use these, and they work a treat: http://smallbear-electronics.mybigcommerce.com/dust-cover-for-16mm-alpha-pots/

I put two layers of electrical tape on the back of my pots to isolate them.

I checked the Delay pot connection and all was good. I checked for solder bridges and resoldered any connection that looked suspect.   Same thing...

I need to try the audio probe as Jacob mentioned above.

Hi...R2 forms a part of the input stage, and could potentially give you a low input volume. It's likely the cause of the voltage inconsistencies Jon had been pointing out.Fix that and start over with the troubleshooting if you still feel it's off.
