Hey guys - I have the control switcher setup with my GCP and GCX, but I'm wondering what to do with the FX loop of the amp (its a Fender EVH 5150 III)

When I have a preset which has the FX loop off and I switch to a preset which has it on; it's fine. But when I switch around different presets it is sometimes on or off, depending which i've just been to. I can end up back on my original preset where I'd want it off, with it being on.

Any tips?

Also I'm getting some hum from my noise surpressor - I had some more hum but we figured out that was the power conditioner/gcx touching the metal of the rack, and the proximity of the GCX to the Furman.

Any help/comments/tips would be great!

The Control Switcher will only control the three channels of the 5150 III and will not properly control the effects loop bypass.

What is the effect routing you have in the effects loop? Do all of these devices run through GCX Loops?
