New tone control for the Tube Screamer

[MmmPedals]

I would like to replace the roll off (low pass) in a tube screamer type circuit with an adjustable one. Now there is a 1k resistor in series with the signal and a .22uf cap to ground.
Does a 100 ohm resistor followed by a 1k pot with the same cap sound like it would do the trick?
Why would I do this you may ask. So I can replace the current active tone control with bass or low mids control. What frequencies would be useful? what's the formula to get the desired frequency?

Perhaps the best thing to do would be to breadboard a son of screamer and see what you can do with those parts and what it sounds like.
