I'm not sure when this started happening (firmware update?) but the output 1 control on my Axe FX XL only goes from 34% to 91% (not 0 to 100 like output 2)...i noticed this when listening to the headphone out and realizing that i couldn't get much of an output volume sweep...I've tried reseting all the factory parameters, reinstalling the firmware, and nothing is changing...any ideas how to fix this? Is there some bigger factory reset I can do?
