I've been trying to learn "I Put A Spell On You" and was trying it out on Thunderbird No 2 (the one with flatwounds) and noticed the input jack was loose as hell and would sometimes cause the bass to cut out. So this morning I tightened it and OILA! no sound at all.
I took the cover off the back and noticed that one of the wires had broken at the jack, probably from the whole thing twisting when I tightened it. It turns out that the wire had not been put through the hole in the tab but merely soldered to it, unlike the other wire which was done correctly. Whipped out the soldering iron, removed the broken end and all the solder on that tab, ran the wire through the hole, soldered it back up and presto bingo, we have sound!
Boy, those are some THIN wires. I used my smaller iron and the thinnest wire solder I had and JUST enough solder to do the job.
Interestingly, I noticed the input jack switch was stamped "Epiphone".
