I'm currently running my Helix LT straight into headphones. No real amp/cab. I've just bought a Strymon Big Sky reverb unit and am trying to figure out the best routing. In the real world, I'd be using my Marshall JCM 800, so would take the signal out via its loop after the pre-amp, into the Strymon, then back into the amp's power amp stage. As the Helix LT doesn't have separate pre-amp and power amp blocks, I can't replicate that routing, so the nearest I can get to that is putting the effects loop block between the amp block and the cab (or IR) block. Is there a better way to do it? Sorry for the basic question, but this is the first time since I got my Helix that I've been trying to use an external effects pedal other than right at the front.
