so i noticed a slight hum through the XLR left out of the axe fx into my matrix power amp. i switched it to the XLR right and the hum went away. upon further investigation the LEFT XLR is slightly pushed in. I'm assuming this is what is causing the issue. my question is, is this something i can open up and put back to where its supposed to be? could it just have come loose or would something have to break for it to push in slightly? anyone else have a similar issue and fix it? any information would be greatly helpful. sound out of it is still solid and consistent just has a slight low cycle hum. thanks for any responses and information!
