So I opened it up and can't quite figure it out yet. Bypass works fine, but when its switched on I got nothing. Any ideas? Pics:

Take a pair of headphones and run the tip of the headphone jack along the board until you find where the sound stops. Hopefully, it's just a dead circuit component. You can get most of that stuff relatively cheep.

That definitely did nothing. I redid a couple cold looking joints and sill nothing. Help?

i would try testing some of the caps, as well as the transistors. the polarized caps may have just gone. some capacitors tend to just go with age, so i would think testing them may help.

bottom right of the pic has two empty holes if you care. also just poke around with a multimeter

So basically if I get a very low or 0 reading on the multimeter that's the bad part?

^And I know, its a replaced jack, the empty holes don't matter.

replaced jack had bad wiring? wrong wire in the wrong hole?

and i think if u get 0v on the multimeter, it might be pretty bad.

at the 9v? do you have a battery in and smething in the input jack?

and worst case scenario: steal the IC's and build a small clone!

You mean while I'm testing it?

Ooh I should check that, cause I bought it that way.

Where does the blue wire from the jack go? It looks like there's a wire missing from the circuit board, one of the 6 holes in the bottom left corner of the board (in the first pic).

It grounds to one of the rubber foot screws. The three empty holes on the bottom left are from the old board mounted jack that got replaced. Only 3 of the holes are actually used, and they're the ones with the wires coming out. The other 3 are just for holding it on the board. Look at the solder side picture.

Btw, I just checked the replaced jack wiring and its kosher.

Hmm... Maybe try a board mounted jack.

If not, try bypassing all the components, to see which one is at fault.

Alright.
What do you mean by bypassing all the components?

I mean a jumper wire that will go from before a component to after. This jumper wire will make the circuit ignore the bypassed componant, as electricity takes the path with the least resistance.
