After setting up the four cable method, the helix and amp sound great together, but I only get a response from stomps I have placed before the send channel. For example, the volume pedal/comps sound good. However, when I try to add delay or reverb after the return stomp, I get no delay or reverb.
I also tried using the 4CM template patch, but I got the same results. Any thoughts on how to solve this?
