Hey everyone, sorry for the late reply. Been busy with some irl priorities and whatnot.
Anyway, I took a look at my crack again and tried to see if I could fix it. I read through the instructions again, and idk if it's just my problem, but they seem really ambiguous. I want to take a picture, but all I have is my phone camera, which is absolute rubbish at taking close up photos. I'll try to describe my setup in better detail.
Right now, I have a 33k resistor between the input and output lugs on the volume pot, for both levels. Should there be another resistor connected to the ground? I also have the 75k resistors in between the RCA jack and the volume pot, but based on Paul's previous information, I'm assuming this is incorrect. Should the 75k resistors be between the output wires and the volume pot?
Here's a quick, poorly drawn diagram I whipped up for further clarification:

Is this the correct setup? The picture applies to both levels.
