I've finally got to play with my AH300 today. It's awesome, but there's some strange behaviour. The front panel has lamps for pre-shape, valve, compressor, effects loop, etc. and the pedal board has the same set of lamps. I'm assuming the same lights should be lit on both panel and pedal board. But when pressing various panel switches or foot switches it's easy to get them out of step - e.g. valve lamp is lit on the panel, but out on pedal board. I press either switch and it swaps over.
Is this anyone has experienced before? Google AI seems to think it's a common problem, but I can't find any real website with information.
