Current Lover troubleshoot

Hi all!

So I just put together the current lover and I get no effect at all when the pedal is turned on. The LED lights up though. I do get a clean signal. I checked the IC voltages and it looks pretty good, except for a few differences here and there. All caps and resistors work only up to C15 and R21. The volume trim is the only trim working.

Here's the ic readings:

IC 1

1. 4.8
2. 4.8
3. 2.4 ...... should be 4.18
4. 0
5. 4.2
6. 4.5
7. 4.5
8. 9.3

IC2

1. 9.3
2. 4.6
3. 2.4......should be 4.85
4. Varies
5. 0
6. 4.6
7. 7.1.....should be 4.2
8. 7.1......should be 4.2

IC3 and IC4 are spot on

IC5, Spot on except for pin 7 was at 0....should be 7.8

IC 6 and 7 are spot on


Could it be a bad MN3007 chip?


Three more things that I should say:

1. D4 is for an LED but the directions show the LED hooked up down by the foot switch, so I just left it empty.

2. I accidentally soldered sockets in at 3 of the trimpot sites, So I just plugged the trimpots in, I would assume that this is totally fine.

3. I drilled initially for the effects loop but drilled poorly so I have a busted dpdt in one of the drilled holes just to fill the space. It's not in use!

Here's some pictures attached. I highlighted all the resistors and caps that are giving me a signal through an audio probe.

Thoughts? Suggestions?

Thanks!!!

Here's some pictures! The last one is the schematic with all the resistors and capacitors highlighted that ARE working. Any help is greatly appreciate!!
