King Of Clone build

[Ed Nine]

Hi. Has anyone here built the King Of Clone stomp box from Clonewerk.com?
The instructions are abit lacking in detail for someone like me who hasn't put one of these together before.

I need to know where on the PCB the grounds go and if any ground has to go to the box itself?

Looking at the photo of the circuit board I see a pad labeled "GND2"... GND is ground. So any pad labeled GND goes to ground. I'm guessing there is a GND1 pad too for the other side... one to each jack.
