Not stompbox, but guitar wiring. Fender TBX mod to Bass Cut values with 250k

[Jamforthelamb]

Hey All,
I've been working on tricking out my MIM strat just for kicks. I installed a Deaf Eddie chromacaster switch in the middle tone position, so now my back tone is a master tone. I would like to install a TBX style tone control in that position that will roll off the treble or bass. I was wondering if someone could help me figured out the values of the caps/resistors if I were to use a cheaper/easier to get 250k blend pot. Here is the schematic for what I'm going for.

Also, I know that the original TBX takes the load off of the pickups when rolled one way, so I plan on installing a push/pull volume pot wired up as a "solo switch". 

Thanks!

Ct should be .033uf or whatever you have that is close, larger value here = greater passive loss.
Cb should be .0033uf or whatever you have that is close, larger value here = less passive loss.
   The correct answer is to BB or just take a couple pots and mount them on a board, build the circuit and try parallel and or series caps to build more appropriate values, or try different values in those positions to get the best response as judged by ear for your pickups.
  "What comes next" can have a big impact on how you might like the response of the circuit.

Do you think those values will work with a 250k stacked. I understand it would be better to get it in there and experiment with different values to see what I like, but that would be complicated because it's a strat, so access to the inside is a bugger to get to.

Thanks!
