Ok so Im trying to use my hx stomp as my cab/IR loader and effects with my tube amp+loadbox. So I watched a video today that made it seem easy. Basically create a send/return block and IR have the input of the guitar going into the mono input then the send going to the input of the amp then return from the loadbox(fryette ps 2) line out to the L return. When I do this I get my amp coming through but tons of feedback. So I feel like I either am doing something wrong or have a ground loop. Any suggestions? basically I would like my signal chain to at the very minimum to be guitar-tube amp-HX stomp cab or IR --> daw. Eventually I would like to have some effects out front and some after the tube amp. Can someone point me in the right direction?
