STEREO FX LOOP QUESTION

    i want to run a few external stereo pedals into the stereo fx loop
    i assign the x module to stereo effects loop and run a cable out to the pedal and come back stereo quarter to xor into the return xlr
    it seemed to somewhat work with a tremolo if i cut the mix down to 50% and ducking to 0
    but the delay just gets the right side even though I'm coming back into the amp stereo quarter inch jacks into an xlr
    how can i get it simple enough to run some stereo pedals and maybe a volume pedal on my pedal board and get the stereo sounds from the pedals
    is it a certain kind of y cable to xlr or is there another way around this

    For stereo effects the input is the left channel and the alternate input is the right, so you need to connect the two outputs of your stereo effects to both of these inputs (don't use the XLR).
