Thanks for the reply gents, I have a Blackstar HT Stage 60 and upgraded speakers with a pair of classic rubys. I’ve rigged it up like you Michael, 1/4 of Helix into the fx return of the amp and guitar into the Helix but I get no sound, but…if I plug something into the front of the amp like I did with the 1/4 patch cable I got sound. I also got sound if I plugged helix send to the front of amp too, not heard any difference in quality either way. I’ve just been jamming for a couple of hours today at neighbour friendly volumes and it’s sounding damn good, even with some of the cab/i.rs i purchased enabled I was floored at how cool it sounded. I’ve been using a Yamaha DXR10 for the last couple of months and it’s a cool FRFR but at band practices I’ve been missing that punch you get from a 2x12 amp behind you. I'll use the DXR as a monitor and I should be all set
