WHAMMY - Grounding

Hi folks, I am at the point where I am wiring the input/outputs of the WHAMMY. I have the WHAMMY chassis that comes with the full kit. I removed the anodized finish where the six chassis plates meet, around the chassis ground screw, and where the volume pot meets the chassis.

Question: Do I need to ground the pcb to the chassis? If so, can I do it by removing the anodized finish where the stand-offs that hold the pcb pass through the chassis?

Many thanks,

John
 
You're welcome!
Also if you're experiencing noise related to grounding, try grounding the volume pot with a wire to the PCB ground. This would happen if the chassis doesn't have enough conductivity to connect the volume pot body to chassis ground.
