Silverhead, what is the difference between "FX Send Function" and "mixer's Send output"....? Right now, I have the guitar running direct into the Mixer Channel Input, a line running from the Aux Send to the POD Go guitar Input and a line running from the POD Go Send into the Mixer Aux Return. I am only getting the straight 'clean' sound, although the POD Go tone is set to distortion. HOWEVER, the tuner on the POD Go is working so it's picking up **a** signal, but not **the** signal.
