I just did the latest firmware update on my Marshall Code 50. My headphones suddenly do not work when I plugged them into the jack. They worked prior to the update. I tested them on another amp and they worked fine. Has this been a firmware problem? Any possible solutions? Thanks.
Hi Richard,
This is not something we have heard of before, it could just be the headphone input failed after the update, but it is not a known issue, we would recommend you get the amp looked at by an engineer.
