As usual, when I ask questions in public, it turns out I was just full of it. We got the back off, exactly as you'd think... by removing the screws. We ended up having to pull on the cord, because we were stumped.

Now I just have to figure out what size nut I need for the jack...

Thanks anyway, folks.

Hi... I'm new here. The input jack on our old Squier 15 amp got loose, and my kid tried to tighten it and it ended up coming out entirely. So we thought we could put it back.

We left the amp sit for two days, unplugged, knowing it can zap you. But now I've taken out all the screws and cannot figure out how to get it open. Can anybody help?
