Muzzle ground issue

Newbie here. I wasn’t going to bother the forum asking because it might be useless, but then I thought “someone might see something.” Any suggestions are welcome.

The issue is when I plugged into the jack on the left (output), I receive a loud grounding buzz. Nothing else is plugged in aside from power. I don’t see any other connections touching. I thought I was also very careful installing all components, etc, but I did something wrong.
My guess is it has to do with the output jack and/or ground but I don’t see anything. Any thoughts folks?

Don't apologize, you'll get there. :)

I still plug pedals in backwards all the time (or forget to plug in the DC) then rip everything apart in a rage because "The damned thing just isn't working"..... It happens.

The wiring diagram on this one is a little confusing anyway and needs to be improved, it can be tough to identify the lugs on the jacks.

Just an added note, if it still doesn't work after turning the TL072 around you might need to replace it. Sometimes they survive reverse polarity, sometimes they do not. Might not be a bad idea to just replace it anyway if you have one.

Thanks for that added note to buy another TL072. It's not like I would know how to test one, right? I bought a bunch of caps, resistors, etc. because I purchased 6 projects from you guys so I'm sure I have another TL072. Not a problem. That's for the suggestion.
 
So I did the following:

-installed a new TL072
-build new backdrop and grounded all.

I plugged into input and output. When off, clean channel worked. Once I engage on switch, sound is fit. What do you think my issue is now?

By the way, if I different angle pic would work, let me know and I can do that. I’m sure it’s something simple that I miss.
