In the most simple passive VT circuit, where both 250K pots are dimed, how would you simulate that system with no pots and one RC filter? There's still some HF bleed to ground with the controls all the way up, but is it just HF bleed from the tone pot, or is there a bit more from the the volume pot as well? I think there must be some HF bleed from the volume, otherwise people wouldn't use no-load pots for volume. I did this for a custom project with no knobs, and I went with 250K for my resistor in this schematic, but it doesn't account for the addition of a volume pot. If the volume was another tone contol, I'd assume I'd want 125K for my single value, but since the volume doesn't have a capacitor path to ground, I assume that changes the calculation, and I'm not sure how to measure it. Any ideas? Thanks!
