I have been playing the black Crumar Mojo Classic in the road case with the inverted for a few days with no issue. Yesterday I plugged in the half moon Leslie switch and it worked fine. Today, I turned on the unit and now the switch is out of synch with the organ and no matter what I do it does not reset or go allow me to turn the Leslie fully on. Is there a reset button for the Leslie function? The manual just shows reset for the keyboards by pressing both manual buttons.
