I have an fx loop 1/2 set up for an external looper, I like to use more than the helix looper. I have it set at the end of my signal chain (right before but I get a phasing sound. I have the mix set to 50% if the mix is at zero effect loop has no sound if it's at 100%. Send and return are set to 0db. If I bypass the fx send phase sound goes away. Something to do with the mix %?
thanks
