    I have read somewhere that on a passive bass the VVT control scheme creates too much circuit load and makes the bass sound dull. Is there truth to this?

    If you want to avoid loading, you'll want a 3-way pickup selector switch & just 1 volume control, but
    then you can't blend like you can with a V/V/T.

    A V/V/T is less loading than a V/B/T.

    The flip side is that not enough loading can lead to a harsh and brittle quality. Most pickups are likely designed with a certain amount of loading in mind. But it all depends on your ideas of what sounds good.

    To my ears, a volume and tone (plus a switch, for multiple pickups) is the minimum. Then there's the 500K vs. 250K Ohm pot question. But I don't think VVT sounds dull--especially if 500K pots are used (for the volumes, not necessarily the tone).

    In fact, on my two-pickup bass, I usually have the volume(s)--500K linear pots--turned down to between 5 and 7, in part because I get better pickup blending and in part to take the edge off the tone. On my single-pickup bass, I often turn the volume--a 250K audio pot--down to 8 or 9 to round out the tone a bit. I suppose that all puts me in favor of a fair bit of pickup loading!

    more accurate to say the controls create some load and thus sound duller than otherwise; whether it's "too much" or not is a different question. i like my fender bass pickups a bit brighter so it's 500k pots for me, while plenty of folks think they sound just right with the stock 250k pots they were designed around.
