Odd Current Lover output issue

[Robusto]

Hello,

Finished the Current Lover recently. Worked great unboxed. After I boxed it, the effected part of the signal went away. So just clean signal with the effect engaged. After some messing around, I discovered that there is some issue with the in/out jacks. The problem is happening when the jacks are installed in the box. If i unscrew them and hang them off the side of the box, the effect comes back. I've tried different jacks. This enclosure is unpainted. Am I grounding/shorting the board with the jacks touching the metal? It doesn't seem to make a lot of sense. I thought about trying to cover/paint the inner edges of the holes for the jacks, but what would I use? Thanks!

Can you post a picture out of the box? And then in?
