Ages ago, I did an A/B comparison in my Strat, if it helps:
This isn't with and without a bleed... but with and without a resistor on the bleed that makes it a LOT more subtle with the resistor in line, and much closer to not having the bleed. I really like having a treble bleed in line without the resistor to make it more subtle - it makes the volume knob much more usable as a way of adjusting the amount of gain on your guitar, and as you roll it back it sounds more like an amp cleaning up and less like the guitar getting softer and muddier. You really can go from a nice gritty clean to full saturation just by rolling your volume knob.
