How to share 1 fx loop between 2 amps

Hi! i was wandering how can i run just 1 single fx loop shared between 2 amps, also using a external
pedal (stereo) in send/return 1/2

here a photo of what i have, my idea is to share the tc mimiq and also the line 3 betwee the 2 amps

my idea is to have the double tracking fx in the loop


Couldn’t you just mix the splitter to row 1 after the cabs and then set the output of row 1 to “row 3”? Then you could place the FX loop in row 3 if you want to have it as a post effect. Finally, set output of row 3 to e.g. multi out.
