I recently bought this effect, I connected it with the 4CM to my 50 watt fender 5150 head! One thing is not clear to me! In building the chain of effects I put the fx loop in the middle, I put an overdrive and a gain before the fx loop and they work, while everything I put after fx loop doesn't work, can someone explain the reason to me? I know that theoretically delays and reverbs should be put after the fx loop, do I miss anything in the setting? I should put it all before the fx loop but I don't think that the delays and other effects are used optimally. Thanks in advance
