cristt, that makes perfect sense. I'm new to live sound so wasn't exactly sure how that would need to be setup on the mixer, thanks!
olerabbit, thank you for the reply! I was just testing using the Amp Out and noticed that it was sending the amp model into the bass amp preamp and "double amp"ing as you said. My bass amp does not have an FX loops, so I activated the FX Loop block (before the amp and cab models) and connected the FX Send into the bass amp input, so now it is not sending the amp model into the bass amp preamp. However, now there is no sound coming out when I test the Main Out/Left into the bass amp (since mixer is not at my house). I've looked through settings but wasn't able to fix it. Any ideas??
