Ok, I have used a helix for the last 4 years with great success and just bought a HX Effects to put in my live rig using the 4 cable method. I was using the Helix for this but it's a bit overkill and I thought I could use the HX Effects for all my needs in smaller package. Not working out! This thing needs to go in the trash. I cannot for the life of me to get the thing to stop feeding back through the effects loop. The effects loop block is sucking the life out of my amp. I've got my global input to Inst, output to inst, send and return to line. I have to turn the return in the FX loop down -15 to -20db to keep it from screaming with feed back on my Friedman BE 100. The Amp has a return level knob that I have to back down to about 4. This never was like this when I used my Helix for effects in 4 cable method. Ive updated to the newest release and now when I go to switch snapshots there's also a slight delay between. What am I missing here? Why is the fx block feeding back? Is it time to send this back?
