LED1 & LED2 do no light up in normal operation because there is so little current running in them. LED3 & LED4 will light up if the Gain, trimmer and Presence are set high enough. Max brightness will be governed by the Presence pot. They will not be as bright as the front panel LEDs.
It's possible that the colors did not all come across correct in the photo, but here's what I see that doesn't look right:
R3A is 1K, s/b 10K
R5A is 3.9K, s/b 39K
R8A is 2.2K, s/b 22K
R9A is 2.2K, s/b 22K
As best I can tell, everything else on the board looks OK.
I can't read R32-R37 because they are in the shadow. Verify that IC1-1 and IC1-7 are both close to +4.5V. If those are good, then check pins 1 & 7 on all of the other opamps. Should be between +4V and +5V.
Can't tell if the switch wiring is correct because the wires disappear out of view. I see an extra wire on the A/B switch, I assume you're doing something clever like a 2-color LED.
I see you are using a Mammoth C10K pot. I bought one from them that was very noisy, so there may be a lot quality problem. Try checking the resistance between pins 1 & 3 in-circuit, should go all the way down to zero when Presence is dimed.
If you get this far and haven't found the problem, then we have to suspect bad parts. The resistors I mentioned yesterday, measure them. It's rare, but resistors do get mismarked sometimes.
Finally, I never trust stamped-pin sockets. If you have an IC that's not working properly, it's more likely that the socket is bad than the IC is bad.
Good luck!
