I would love an answer as well. I've seen all the videos, read the manual, running an amp shouldn't be this difficult. Also tried running one fx loop vs separate send and return....line level vs instrument level...nothing fixes it. I'm not even using the amp's (Carstens Grace) power section. Just trying to get the preamp into the helix. But as soon as I crank the master volume on the Helix to about 5 o'clock....squeal city. Even with it turned down, if I use a delay, it turns into a mess as the delay picks up the squeal and it gets nasty fast. Tried every loop, combo....I'm out of ideas. It really sucks having an awesome amp that I can't incorporate into my rig :-( Any help or ideas on solving this are appreciated. I guess it helps to know that I'm not alone in the struggle.

I am looking at getting one myself and I think, based on researching what the helix is capable of with out-board pedals, that it is possible. If you get the chance to try this, please let me know if it works. My thought is, setup your patch with a clean amp model/cab, etc. Hook up the vh4 pedal as such fx send 1 to guitar in on pedal. Return 1 to "to clean amp" on pedal. Then use another cable to hook the "remote" out on the pedal to the ExtAmp in on the helix. Use the fxloop1 block in front of your amp model on the preset to toggle the pedal in and out of the signal chain. Then go to the command center on the helix, select the footswitch that you want to use as the control for the channel switcher. Set it to "ExtAmp" and it "should" work. Again, I don't own one of the vh4 pedals yet so if you get to try this, please let me know how it goes. I'm very curious. BHD
