Ross Comp: 50KA or 100KB for volume pot?

[DeeBug]

Tonepad calls for the 50K log, whereas at Fuzz Central the parts list and schematic show 100K linear.  Otherwise all the parts appear to be the same.

So, I'm left wondering, which one should I go with?  What's the diff?  They can't both function exactly the same way, right?  Which is the one to go with?

Thanks in advance for any insight into this!

Doesn't really make a huge difference...
  50k volume pot = 50k from signal path to ground [through the potwafer], so this will shunt a touch more signal, making output slightly less.
  100k = 100k from SP to Gnd. output is slightly more, and as a result you're likely to have it turned down more, which equates to a higher resistance series W/signal path which can make a slight LP filter...which can be bypassed with a small cap, even made to 'treble boost' with a slightly larger small cap across the input/output of the pot.
  So...either one is just fine IMO.

Stock is 50kA.  100KA or B will "work", though several things will result:

1) if you go with a B taper, the change in volume will be scrunched at one end of the pot, rather than evenly distributed across the whole pot rotation,

2) If you try to use an added cap in parallel with the 10k resistor just ahead of the output pot as a way of getting back a bit of treble, a larger value output pot will reduce the audible impact of that additional cap will be significantly reduced.

everyone seems to loose some trebble on the Ross comp.... i'm loosing some bass?! (very little but still...)

You can try a bigger output cap.  JC Maillet points that out as the bottleneck in his dynacomp page:
