Question I have a G-Major 2 which I am going to run in stereo with two amps. Some sounds will be in mono using only my main amp and some sounds will be in stereo using both my main amp and the second amp. Is it possible to have the signal muted in one of the outputs (e.g. right channel ) and have this stored in presets  Answer On the G-Major 2 we do not have a separate volume control for left and right channels. So unfortunately, it is not possible to mute one of the channels when you are going mono. Both outputs will always be fed. To achieve what you want, an external device should be added. Note that both the G-System and Nova System has that feature.
