Hi all. I have owned a Line 6 LD300 Pro since 2012. Actually from the beginning I have been having problems with the control knobs. Therefore, the amplifier serves mainly as a stand for my TV. Problem is that the channel knob changes position without me touching it, the output volume is suddenly extremely loud and so on and so on. If I change settings or choose a particular channel, it goes fine for a few seconds/minutes, and then the amp switches to another channel spontaneously. Reset to factory-settings I have done several times (ON+ChanA) but that doesn't solve anything. Does anyone know if there is anything that can be done about this? Can this be repaired by an expert or is it a software problem and might require replacing the entire circuit board? Super thanks in advance.
