Thank you, voxman55, for offering help. I wonder if I am missing something even more fundamental here than simple DSP usage. I am aware of how the loops won't carry over between set-ups. I have removed all the effects other than the loop as a test, and the looper still does not even offer an "on button" and it is greyed out. I attached a screen shot of the editor. Even the amp model is turned off. Note that the Looper is early, and grayed out, and there isn't an "on" button next to the X. Puzzled.
(...PS I have been using loopers since tape loops in the late 70s, to the EH16S, various Jam-Man, Looperlative, Boss and I still have three Line 6 Echo Pros...I would love to be able to tour with just the Pod Go for my lap steel guitar.)
