The HXFX output goes to the return of the stomp. So it won't affect the amps in the stomp. It will only affect the Dyn and Mod.
It is the HXFX send that goes to the input of the stomp, before the amps. So I guess, that is what I should be setting to LINE?
My apologies, I've updated another "DO" stomp patch as I noticed there was no FX Loop block but an EQ instead.
I also uploaded a new stomp photo to show the correct block used. Will this change any of the advised you guys have given?
So you won't have to scroll up and down, I'm uploading the image below:
