Should I use a buffer for a passive volume cut?

I have a BYOC 5 knob compressor. I'm going to put it in a box with a passive volume cut. This is just a pot wired as a voltage divider to ground. Both the compressor and the volume cut will have their own stomp switch. 

If I put the volume cut AFTER the compressor what value pot should I use? It looks like the output of the compressor is buffered. This being the case, should I use a buffer on the volume cut? If so, should it come after the volume pot?

Ah yes, the problems of bringing up BYOC here...

I wouldn't ask BYOC because really this question has little to do with BYOC aside from the effect's output impedance. I only decided to mention it in the interest of providing further insight into what I'm trying to accomplish. Assume that the compressor isn't even in the equation, my question would still be the same.

"If I put a passive volume cut after a "buffered pedal" what pot would be recommended, and would a buffer be advised after the pot".

I'm no expert, but I guess it depends on what kind of effect you're gonna be using it with. In your case, I'd say no need to buffer, just pop a 100k pot in the output. :)

I may have been too ambiguous. This essentially will be a passive volume pedal in a stompbox; just a pot and a few wires. When switched on it will cut the volume by about half (or whatever). I was wondering if placing a buffer beside it might avoid the treble loss that usually occurs (and sound more natural than a treble bleed cap). What I was saying with regard to the BYOC comp is that there will be a buffered effect both before and after this pedal so I wasn't sure if a buffer would help much.
