Update:
Well I predicted I would need your collective help. Here is where I am at:
- I built the entire circuit on a breadboard (see picture).
- It does not work
- I was extremely careful with the following the schematic, but that is not to say I have not made errors. I plan to carefully look at the breadboard connections when I get some solid time to do so.
In the interim, here are some things that I came up with that may have caused problems:
1. As you can see , I used different kinds of capacitors, depending on what I had available. So, you will see that i have used ceramic capacitors and polarized electrolytic capacitors. I wonder if this is causing the issue. If it is, I am happy to go buy the right capacitors, but I am trying to figure out what they are. AudioGuru advised that ceramic capacitors should not be used for this purpose.
Should I be buying non polarized film capacitors for every capacitor value called for in this schematic?
2. I am not using the same op amp that he used in his schematic. But in his video, he was swapping out op amps on the fly. He said that having dual op amp ICs, enabled him to pop out one op amp and change it for another, on the fly, for comparison purposes, So the Op Amp I am using, is this one:

I downloaded the data sheet and was careful to ensure I was using the right pin mappings.
But can this be causing a problem; the fact that I am using this particular op amp?
I can't think of anything else that could have gone wrong.
Thanks for hanging in with me. I am learning and sometimes the best way for me to learn is trial and error.
P.S. I am also learning a lesson about breadboarding. I recognize it as a valuable tool, but I think that when you get into so many components and connections, it gets hairy trying to make all the components connect properly.
I am tempted to switch to a virtual breadboard (using Everycircuit).
