Okay, thanks for the advice guys! It is an Epiphone (G400 Goth) indeed, which is why I'm hesitant on spending a lot of money on it. The quote I got for the repair was over what I paid for the guitar itself. I think I'm gonna check with another guitar tech to see if he charges less.
I do have some cool mods on it that I really liked, so that's why I really want to get it up and running again. Here's a picture of it in better days:
I even bought a second SG to perform the same mods on to have a back up for this one. Hope to have some time to build that one in the near future (I'm planning on doing another finish on that one though, so I'll have to figure that out first)!
