Okay let me ask in a different way. I want to have two effects chains running simultaneously. One from my guitar to the instrument input on my amp. For the next loop i want use the effects loop on my amp. The problem i am trying to solve is that I spent good money on an Amp that is modeled in HD 500. So i want use the actual preamp for clean and crunch. But as we know some effects are more effective between the guitar and the amp and other effects are more effective in the FX. So i am looking for a way to get that flexibility.
