Ibanez SR300DX issues

So basically I have a modded Ibanez SR300DX with the J pickup swapped out and P pickup reversed to put it in phase. After attempting to shield the internals and then undoing the process mostly I've found that the blend knob is no longer working correctly. I have done no soldering and all connections are insulated and in place. Basically I only have two options, P pickup and J pickup, or J pickup, for some reason instead of blending the pickups it more works as a volume control for just the P pickup when it used to blend just fine. Can anyone help me with this?
Update: The P pickup has stopped functioning entirely now.

 

I do not, sadly

 

At this point I am just gonna rip the two volume pods from my shortscale parts bass and just do a full rewire of my bass because I just had two wires snap. I absolutely hate the wiring of the SR300DX, but love the tone.

 

So here's an update, I am just going to rewire the bass to my best ability.
