First of all - 'calm down dear' - I'm sure you could play a lot more controlled!
Second - not exactly low profile or pancake, but very solid and well made, the best bass lead I ever had and always use; https://www.amazon.co.uk/Vox-VBC-13BL-Class-Professional-Cable/dp/B000Y7RQQA
Better than many if not all above that price range IMHO.

Use the good loom wiring as a reference and copy that π
If you seriouslly overheat the pot when soldering it can go either way, short or open circuit or just erratic. Have you got a multimeter?
That'll be a wire to connect the shielding paint to a earth point, connect with the bridge earth and pick up -/common/earth.
There's nothing 'wrong' with what you've got, I would use the other tag on the tone pot, (swap the white wire to the other side tag) and make sure nothing is touching earth or the shielding when you put it together - that's the problem - position the pot tags away from the edge and it should be OK.

Oh yes, forgot about that, we're on our second, first lasted 9 years then seemed to go too firm! Bought the same make again, Ergoflex.
So with the mattress and Down pillow we should be in bed heaven π
I'd bet on it being a set up issue and no way - a buy a new bass issue!
Neck - trussrod - frets - nut - bridge or even strings, that's all π
or it could even be just the way the E string is fitted π
I don't think they would 'damage' the neck - personally I don't like putting heavy strings on tiny necks though, just ain't right in my book. Where have you got your tensions from? Check on the page below:
