to @bobcoss I'm new to the helix, and I think you may have simplified it for me, just came acroos your post, Thanks..
I've been effect looping for years, even have bounded nice double cables to and from the effects loop of whatever amp is in front of me! You are saying...I can utilize all the effects in my helix floor running straight out, 1 cable, to the return of said amp head? I mean, I love the sound of delays and chorus going through effect loops instead of to front of amp (preamp) Why then would would I have to set up another block in helix (Send/Return)? Can I just plug and play thru helix to amp return and get rid of that block and 4CM? Please advise, and thank you.
