Does this diagram make any sense

[so_rockstar]

I'm looking for the best way to set everything up with the GCP/GCX, and so far this is what I've got.
The mark IV has a switch to permanently enable the FX loop, thus making the 7th and 8th gcx loops seem redundant as I could place the Quadraverb directly in the Mesa loop and not run through the GCX...this diagram assumes I have the stereo mod on the last 4 loops (or at least the 8th loop)

Is there a better way to do this? Assuming the Quad is the only effect I have in the loop could I do this via the un modded gxc?

Most of this is correct except loop 8 as you suspected. There is no need for using loop 8 to switch the processor nor is there a need for the Stereo Mod if you are going to control the FX Loop bypass with Loop 7.
