Pork Barrel that won't do chorus

I've got a Pork Barrel that won't do any chorus. It will pass normal sound when activated, but that's as far as it goes. I've added some mods to this thing, the deep mod and the vibe mod. When I activate the vibe mod by the way all signal stops altogether.

Some gratuitous gutshots to aid in troubleshooting:




Wiring for the pots is always color coded in my builds, yellow for lug 1, white for lug 2 and green for lug 3. I'm huge on color coding my wiring, makes things more manageable. To and from board is always purple, In/out always grey, red for power,  black for ground, orange, blue and brown for switches and mods.

Any help to get this one back on the road is very much appreciated!

Can't see you pictures. I had a similar problem: the input on pin 3 to the 3007 was there but there was no output on 7 and 8, turned out to be a bad connection in the jumpers area, finally tracked down with a multimeter  - what revision is your PCB? If you can trace the audio then you can narrow it down. Posting IC pin voltages might throw up some ideas.

The 3101 is backwards.
D1 is backwards
between those two I'd say it's a no worky yet.
