The circuit is correct.  To answer the question in red, no.  Those points are not grounded.

Where are the points in red going to?

Well, I'm back in the US, but it will still be a couple months before I get back into my storage unit.

When I do, I have a Fulltone '69 pedal that I can open up and tell you for sure. That is, if you can wait that long...  :grin:

No rush. I heard the 69 was just a fuzz face with a Contour & Bias control

HBP time is all we have. Thats the one thing we cant control last time i checked

Of course i am watching the old OUTER LIMITS.

Once I stopped and actually looked at the schematic, the arrows appear to point to unused legs on pots. So they don't go anywhere.

It also looks to me (though I could be wrong and will double-check) like the "Fuzz" and "Bias" pots have their labels swapped.

HBP is right the unused lugs go to nothing.  They are just variable resistors this way.
