My Spider Jam changes to Twang Red Model when I first turn it on. It will go to that model 3 or 4 times, when I turn it on. I change it back to a preset and it will stay there for a few minutes, then it’s changes to Twang Red again. I have :done factory resets, reloaded the firm ware, taken it apart and checked all connections, especially the ribbon cables, loosened the amp to cabinet screws a bit in case they were causing stress on the amp components, tried plugging in an FBV Express pedal. Anything else I can try?
