I'm curious, does any one know the values of the resistor and the cap that are packaged with the TBX pot? I'm looking to copy using two pots.

Hi setain, I found some information here, although I cannot speak to it's accuracy: alexplorer.net/guitar/mods/tbx.html82.5 kOhm resistor 22.5 uF capacitor Dan

The resistor sounds about right.
However, the cap should be 0.022uF NOT 22.5uF.
0.022uF is the same as 22nF.

Just for kicks, if it was 22.5uF, what would it sound like? Just complete mud? Or super "fat"?

Or, you might have a fancy volume, since it's possible (off the top of my head) that a 22.5uf cap would let pretty much everything in a guitar's frequency response bleed to ground.

That would be highly true! Assuming very minimal inductance values, the usual cap value for a full bandpass of audio frequencies is 22µf. That translates to allowing everything above 32Hz to pass through (give or take a Heinrich). That value is not cast in concrete of course, but it's close enough to start with, in most cases.
