    Has anyone converted their Jazz type bass to an overall volume, balance, and tone control? I like the tone of my Jazz bass but hate screwing around with two volume controls.

    Ive done it. I always run neck 100% and dial bridge to taste, usually up where it’s still humbucking and adding bark but back enough so its not too nasal. Right there, i always get the fat ltest sound which i prefer. Blend works great for this. I’ve noticed no degradation of tone.

    Blend will limit you from the nearly infinite possibilities of two volumes though. Everything is a compromise.

    I don't know why this myth persists. There is literally no mix of pickups you can't get with a master vol and blend that you can get with two volumes.

    I have a Stingray clone that was wired like a J-Bass, upgraded the pickup and converted to master volume / master tone. Love it. I also have a Fender J-Bass but I like having the 2 volume controls on it.

    Because it's not a myth.
    A volume / balance has three resistances connected to ground, while volume/volume is only two.
    Those mixes you think are the same with a V/B won't sound the same as a V/V, because of more degradation of the signal (leaking to ground).

    Because one pickup is always 100% on and only the other is attenuated. Not so with 2 vols. Nature of the beast.

    However, it’s not noticeable as there’s still lots of tweaking to be had between the blend and master. But adding another resistance path changes the game.

    That's tone, which of course you're right about, but we're not talking tone, we're talking the mix of pickups.

    Personally I hate blend and master volume in a passive system because I don't want to run my pickup through any more pots than absolutely necessary. But purely in terms of being able to select any amount of either pickup, there's no combination you can't get with MB you can get with VV.

    Literally false. Turn down the master and that pickup isn't at 100% anymore. There is no mix between the two you can't achieve.

    There also is no need to have 3 ground points on a CBT setup, since the blend doesn't require one.
    I have studied, measured and debunked this legend more times than I can count but people tend to be stubborn about it.

    If you don't ground the blend pot you can not fully solo one pickup, because the one being attenuated is never fully shut off. We're not stubborn about it, it's Physics:

    With me a JB is a set and forget bass for the most part. I’ve got both volumes at 85% and the tone dialed to taste. After that it’s in the hands.

    Some folks do volume swells with the bass's volume knob & TBH you could with two volume knobs, but it would mean having to lay a finger or side of your palm against both knobs & roll them simultaneously.
    It might not be so elegant, but neither is three-string chords with your fingers (which people do).

    I went from VVT to VBT when I changed my pickups to Wildes. This works great for my purposes since I tend to run my volume on 10 and pretty much only use neck pickup soloed or an equal blend of both pickups. One volume knob to kill the sound or make a small adjustment is ideal.

    uh, yes and the dimmed pickup output drops the same amount resulting in the same pup mix, just quieter.

    You should try it and see how it works out for your use of the controls. There are pros and cons with both methods.
