As the title says it, I'm having a HUGE PROBLEM with my amp.  It keeps turning off and on, off and on, off and on, off and on... and it keeps going.  When it does finally work, the presets start mixing around by themselves.  I'll be sitting there jamming it up, and then it changes on its own.  then it continues, adjusting the elay.. by itself.  Adjusting the wah... by itself.  Changing the channels.. by themselves.. then the led lights start blinking, not the tap button, every light that is lit up starts to blink and starts to dim.  Even the orange display begins to dim, continuing to change my amp around like some maniac is controlling it, then ultimately, beging the turning on and off cycle, and then repeats again.  I don't know what is wrong with this amp, but it is VERY frustrating! I've already updated it to the max, wiped EVERYTHING, then updated again.  It happened again, so I reset everything, replaced guitar cable, and still the same thing.  My friend has the same amp as I did, I used his power calbe, and the same thing happened.  I don't know what to do.  Thanks for reading all this if you did.     

     tl;dr:  My amp is going crazy as hell, and I can't do anything to fix it
