Hey guys, i have a line 6 spider 3 amp and the guitar input has come loose and fallen down inside the amp but i'm not sure how to open it up to fix it. I was wondering if anyone here could offer some advice as to how i might go about it.

I had that happen to me on my old Line 6 212 Spider Valve. I dont how how similar the two amps are to be honest but I just pulled out the "head" portion of the combo amp and just screwed it back on. Or you could take it to an amp tech and they will do it for like 10 bucks lol.
