It shouldn't cause a big difference in output level, the concern is dialing in too much resistance "inline" on the way to the amp which will cause your cord's capacitance to have a greater effect. That is, what matters is the part of the pot's element between the input to the pot and where the wiper is. Obviously this will be half as much with a 250K pot.What would be the benefit of lowering the resistance of the circuit? Would there really be a noticeable difference in output level?
But Ash is right in mentioning ungrounding the pots. I suggested this to him when he was trying to use one of these balance controls as a pickup selector. It's better to have only one pot act as a voltage divider and the others work as rheostats. Each voltage divider loads the pickup, and too great a load suppresses the pup's resonance. Used as a rheostat, the value of the pot won't matter, except a larger value will give you more "off".
Hopes this helps, I'm running off to work and just blabbering as I finish my coffee.
