I think you want both capacitors to be 1 microfarad. This will give a bass roll off
at about 16 hz if the input impedance is 10 k ohm. read the description at
http://www.mindspring.com/~tidmarsh/binmic/
If you have to have variable output, you could bridge the output with a
potentiometer say 10k or so, with and audio taper and connect the wiper to the
capacitor. You can't get gain out of a passsive circuit, you can only fade it..
I think you'd be better off making with out that though, because it will make it bulky
and you get little out of it.. I show the modification on the circuit below if you
have to try it. I haven't gone through the math but it should work.

Not just another pretty mandolin picker.
