Hello, I just purchased the CODE 50 amp, and downloaded the Gateway app. I've only had about an hour and a half to play around with it so far. But I was unable to get the tuner in the app to pick up any sound. I have been out of the "scene" for quite some time and may be using it incorectly. Yet I can't find any help or manual for the tuner. Any help would be greatly appreciated.
Did you connect the app to your amp? I believe it does not work as a stand alone tuner, it has to be connected to your amp.
