Has anyone had issues with their JTV69 frying boards? Twice now I've fried the main board. It's still under warrantee so it's getting fixed for free but I'm starting to question the reliability. I am using the ABS To power it up through the supplied1/4 cable. My technician insists there is nothing internal to the guitar that would cause this. The issue starts with what looks like an internal com issue where I can't access the guitar models or alt turnings until I play with the selector switch then they work as normal. Eventually I cannot turn off the guitar by pressing the model selector. To turn it off I unplug the cable. At that point it Will not turn back on. It's in the shop now so I wanted to ask if anyone has experienced this. If there's a hardware fix I want to let him know. I have a feeling that I'll just keep blowing through boards.
