I have had an X3 Live for maybe six months, love it. Been using it at home, no problems at all. Took it to a gig Saturday night, turned it on, all the upper controls (rotary knobs) seem to work fine, none of the lower footswitches worked, no LEDs lit, no tuner, no pedal function. It did make a generic clean tone when I turned it up, but unable to make any of the footswitches work. Has anyone heard of this, or know a fix? This is all I know about it. Thanks in advance.
