Hi thanks for responding,
The GSC4 split mode works very much like the hx stomp. The GSC4 has 6 ins and outs for pedals with the option of splitting them into two sections. When its in split mode the in\outs on the 3rd loop are used as the send to the front of the amp(out) and the amp fx loop return(in). The GSC4s output is sent to amps fx in. split like this the GSC4s loop 1 and 2 go to the front of the amp and loops 4,5,6 through the fx loop.. It works great and this is how I have it set up. I've tried inserting the Stomp to the signal flow of the GSC4s routing by using its own fx signal path which I wasnt able to make work. I've also tried inserting two un-merged, separate mono paths from the stomp into each section of the GSC4 and also wasnt able to make it work. I know its got to be something Im not doing right but cant to figure out what it is. I hope I explained that well enough, thanks again for the help.
