I just obtained a tube amp pedal with an effects loop. I want to run a couple of OD, distortion pedals before the amp pedal and use my Helix Stomp for all my time based effects in the effects loop, kind of a 3 cable method if you will, with the final output going to the DI on the amp pedal. My question is, do I use the input/output of the HxSt or the send/return?
