Ok, maybe its not that serious, but since i've had it it does his thing where the gain control for the ultra channel will suddenly become disabled and the light will dim. When this happens the gain is being controlled by the crunch
gain knob for both channels 2 and 3, but when its working, its independent like it should be. As of now its not working, and I don't use that channel barely ever but I'd just like to know what is wrong with it if anyone knows. Thanks
