I apologize if this is a dumb question, but I do not know a lot about guitar maintenance. I have a 7-string electric guitar (Jackson JS22-7). Ever since I bought it I noticed when plugging it in that the output jack wobbles a bit. I picked it up the other day to go to a lesson and saw that there was no jack, just an empty hole. I took off the screws on the back to see if I could quickly figure out how to get it to stay there but could not.
I have taken several pictures of the situation and attached them. If anybody knows how I can secure the jack in place so I can continue playing this guitar I would appreciate it very much! Thank you.
