    I would use the TVJ wiring rather than stock if they are different and I believe they are. If the original wiring had the muting issue then you need a new schematic. That happens on my electromatic but not any of my 3 prolines. that may solve your bridge tone issue as well.

    I'll have to look them up.

    BTW - I get a bit of shelving myself on my 6128 and I have everything exactly to spec per the TVJ wiring diagram. Volume is pretty smooth on individual pickups, but when blended, I can definitely hear the one pickup kick in as I turn it up.

    However, I did look on 920d and they say:

    "Lastly, our pots utilize a 10% audio taper so that your volume or tone sweep can be slightly shorter. This allows for a faster sweep but still maintain plenty of control to fine tune your sound."

    I'm not sure if that has anything to do with it but I also have a custom taper on my pots but not sure if it's steeper or not. I'm thinking about subbing in some Tocos pots on my 6128 to see if that changes the behavior.

    Unsolder the pickup from the harness and solder it right to a jack, then you'll know if its in the harness.

    And by doing that, you will change the impedance of the circuit significantly - I would expect an audible difference even with a known good harness.

    1. Measured impedance with this harness, aligns perfectly with TV's spec (5k neck, 7.7k bridge).

    2. Compared this harness to the TV jones "tone pot" harness (https://tvjones.com/tone-pot-harness/) and it's identical except for a treble bleed added to the master vol pot. Would not explain why the neck pickup has plenty of top end clarity but bridge does not, though

    3. Pickups are quick-connect and I'd rather not butcher that to test a theory :(

    It will tell you if the pickup is something you can work with or not, if it sounds good pure then you can tweak your components to taste. It works for me.
    Nevermind.....

    thinking of just doing a 2 pot wiring setup, master volume and master tone. Anyone got a diagram for that? I'm having a bear of a time finding one!

    A bridge Power'Tron is my favorite TV Jones Filtertron style pickup.

    Wanna buy one in gold? Or the set? I'm learning the powertrons are just too dark and middy for me. Probably gonna just get some classics.

    I have a factory-stock Powertron in my 6119 bridge-position and it sounds absolutely smashing. Great hights, mids and lows. No problem at all. One of the nicest pickups in my book.

    Follow this minus the jack socket

    Then add the tone pot and jack socket as in this

    I have done it in this guitar and it works fine

    Just one thing: you told the neck PU was exactly what you wanted. Your bridge PU is not Powertron but Powertron Plus, especially made for ZZTop gitarist, supposed tot have more heavy sound. Just a normal powertron on the bridge could help you out. If you having too much mid tones with a normal powertron there, then you could move to classiic/classic plus.
