UPDATE>>> somehow the internal processor for the footswitch got corrupted. I suspect the electrical ESD generated during connecting/disconnecting. It is important to connect the footswitch first and then power on the amp. Making sure the footswitch cable is unpowered before the connection. Otherwise, fluctuation of power in footswitch cable during plugging on/off will toast the onboard chip from the footswitch.The components in my footswitch are still good but the programming got corrupted. So my footswitch is bricked at this point. It needs reprogramming. I will check with the manufacturer about reprogramming it (if they even offer the service). These footswitches are discontinued so i will have to hunt for another one in the wild. wish me luck.The footswitch itself use SiliconLabs C8051F314 processor for switching functions. The programming is hard-coded into the processor so I will not be able to just swap a new chip. It will not function as intended without correct programming. It use serial communication to communicate with another C8051chip inside the amp via TS cable.Attached file is the spec for the C8051 chip
