    The price important.

    I put $225 into a 5-digit handheld model B&K was discontinuing in 2002. I still have it.
    That functionality in a handheld costs $200-500 today.

    If you want that last...

    Slow decline.
    People who like electric guitars are dying off.
    The newer gen uses sampled sounds in large part because of their ubiquity and convenience.

    Yes, it's a magnetic field soak to decrease the B,G string contributions.
    Lacking adjustable screws, it's an economical pickup tweak.
    The StewMac picture helps explain things.

    Those range between 300-500 maH capacity and could be matched by 3 lithium button cells.

    Sure. I suspect that a resistor value near that of pickup coils would be best.
    That leaves a lot of wiggle room, I'm guessing 1,000-10,000 ohms.

    The tough wire is APT, Armored PolyThermaleze or the heavy build HAPT.

    An inductance meter (LCR) can suggest how far down the cut-through is, but you'll have to do some disassembly to find out.

    $110 0-2000g (0-200 mT) gaussmeters are commonplace on eBay. Make sure you read the specs to confirm that they read DC gauss or Tesla. ELF meters are of no use for testing pickup magnets.

    These days, I follow the Principle of Maximum Laziness and would have looked at the Arduino PID sketches for ideas.

    Searching on "arduino PID autotune" is instructive.
