Hi guys,
I was practicing some bass when I suddenly got called, I left the cable in the input. Then i returned while on the phone, and i accidentally stepped on the cable, exactly there were it meets the input, and it gave a loud ''CRACK''.
Since then the input has been infirm and I cant put in the cable anymore because I simply press the input into the bass, so it wont say ''click''.
I know it was stupid to stand on my bass

, but can someone please help me with this, because I have no clue what to do. I actually like screwed of the steel sort of plate around it to see if I could do anything about it.
Thank you

P.S. I've been looking for a while to find a sollution on this, but didn't find it, the one page I found was in pretty hard english, and without pictures, which made it hard for me (and my crappy english) to get.
