I am not an expert, but I really don't find anything interesting on 1M pots. Maybe if you are a dog, or a bat, you will notice some extra brightness, but the taper of the pot is not good at all. If you are a guy that uses pots a lot, its better to bring back your treble using some other methods, like installing an onboard buffer in your bass.
I really don't want to add an active circuit, I just want to "take the blanket off" these pickups, so to speak - while retaining the ability to blend them, or roll them off altogether in some situations(on stage or at rehearsal)
At any rate, it doesn't look like anyone here has ever actually tried a 1 meg volume pot with a TB Plus pickup, so I might end up being the guinea pig... I'll be sure to post the results if I end up trying this, though...
