    Treble bleed is not the same as a tone circuit. In a treble bleed, the resistor and cap are not in series, they are parallel, and they do not go to ground but are inline with the hot signal. It’s a different circuit that serves a different purpose. The only thing they have in common is that they are defined as RC networks which function as a filter, either high pass or low pass. And a treble bleed does not create a resonant peak.
    The bleed circuit can just as well be R+C i series and in parallell. It's the time constant that matter. I've done a couple as series bleed circuits.
    And since I experienced it myself, how not only highs were affect by bleed - coils in pickup play a roll.

    It's all one circuit - where different parts serve different purposes.
    - pickup serve as generalting tone from strings
    - volume knob allow to adjust volume level
    - bleed circuit, if there, compensate loss of highs as volume is turned down
    - tone circuit allow to send more highs to ground, making tone more mellow
    - cable allow to transfer of guitar signal to amp

    changing parameter in one of these above - will affect the full circuit and what signal to amp contain.
    With volume on 10 bleed circuit is shortcircuited.

    and since pickup is coils that is part of circuit as well - you can see, as freefrog added diagram, you see that pickup coil also play a roll and can create resonances.

    Dealing with active pickups that circuit is more like out of the equation. But for passive circuits it's all affecting each other changing one component.

    One sample Fender bleed circuit
    https://www.fender.com/articles/tech...fect-your-tone

    A combined R+C in parallell and in series with another R.

    I have not checked, but have a Fender Shawbucker Tele - that has bleed circuit as delivered - it might be the same.
    It might remedy the not perfect result I got with my hollow body bleed circuit - also changing mids a bit.

    I'm not going to trust some guy who couldn't even figure out how to wire up a neck pickup.

    Ed was quoting Duke Ellington when he said that.

But not when only the neck pickup is chosen.
    Thinking about doing the same for my 20th Anni Custom 22 - mine has Antiquities in it too.
