Grounding in multi FX box

[shawsofhell]

I am currently in the final stages of constructing a multi-fx box that has relays controlled by a microcontroller in order to get patches of effects. I want to ensure I have the cleanest signal through the whole system and I am currently pulling out my hair trying to work out the best way to rout ground wiring. I have included a picture of how I think I will do it. This has every ground going to the same point on the Power Distribution Board. Your comments would be appreciated.

Cheers,
Chris

Is that the In and the Out of the entire multi effect? That's how I wired mine. Star grounding I believe, quietened my setup quite a bit.

Sorry, yeah the in and out are for the whole box. I only showed one effect coming off the switching board.

Green = ground
Blue = signal
Red = power
