Help solve hum problem on pbass

Invalid Link Removed

Ok, I took my pbass apart to look at the wiring. It doesn't appear to be wired like the pdf file. I am thinking that might be why it is humming.

It appears the volume pot is wired correctly except the capacitor is going from lug 3 of the volume pot to lug 1 of the tone. According tot he pdf it should go straight to lug 1 and the capcitor should go from lug 2 to ground. Other than that i believe it is wired correctly. Would that cause the hum?

Background on the hum. The hum would go away when I touch anything metal on bass suggesting a grounding problem. Well, if the wiring is wrong that would be a good reason too.


Edit: here's a pic of my wiring if you can see it.

SWEEEEEEET!
I decided to change the wiring to what I thought was correct according to the pdf. The tone knob actually does something now.
It use to do something but not much so I thought it was a worthless knob. And there is no more hum. And now that I have flatwounds on and more tone control I can get some deep bass. I like it very much :)
