Voodoo Lab

I would like to thank in advance the people on this forum for helping me and everyone else out. I know it can get frustrating answering so many questions.
I had posted about a rig Im setting up. I think I sort of understand some of the logistics now.
Ive added a second GCX, plus two amp switchers. What are the problems with my map (I think I probably have the second GCX hookup wrong)
I think the VL amp selectors will take care of my ground issues, hopefully Im grasping how this works a little better
the boogie and peavey are straight to the amp switcher, I had to rework the image a bit in order to get it small enough to post.
and also I should have labeled them amp selector instead of switcher
Thanks

This should all be fine. Right on! The only thing that I would change would be to run the rear panel Feedthru of GCX #1 directly to the input of the tuner. It does not need its own loop to turn it on and off in this case, and silent tuning can be achieved by turning off Loop 3 on GCX #1.

Thank you very much
I really do appreciate all the help
