I have a DT50 212 and recently picked up the pod go. I'm attempting to use the 4 cable method (yes, I am sure I have the cables routed correctly). It seems like I am not getting any tone from the amp (none of the controls affect it, including drive, channel vol, and master volume) and the only way to change the volume is with the volume knob on the pod go. I was hoping to be able to use the amp tones in the amp and use the pedal for drive/boost and wet effects. I have even disabled all of the effect blocks and the amp/cab blocks in my Pod Go preset, and nothing changes. What am I missing?
