I have an X3 Live, recently the star that shows changes have been made to a tone has been showing, although I haven't changed anything. The tap tempo button was having an issue so I figured that was the problem had it fixed by a certified Line 6 repair tech. The problem still persists. The tone doesn't change on the unit. But If I should ever decide to sell it or trade it I would like it to function properly.
Note: I have done a factory reset.
