Okay so I have started having this strange issue with my Mark IV. Sometimes when I turn it on more than one of the channels lights will be flickering and it makes this buzzing/popping sound. If I pull the FU-3 foot switch out while it's doing it then it will stop. This was happening for a while when I was using a wireless and then when I went back to a cord it went away for some reason. But now all of a sudden the problem is back even when using a cord. If I don't connect the FU-3 and just use the manual channel dial on the back of the amp it always works fine.
Has anyone experienced this same issue or heard of anyone that has? If so, what did the cause of the problem end up being? :?:
