I stand corrected ;-)
...but
1) this formula doesn't tell you log or linear. 
2) just done some experiments with a Filter Pro, some vol pedals
    and an ohmmeter. 0 to 10k won't give you the full range, you 
    need 0 to about 16k. With the line6 Filter Modellers its very easy 
   to tell if you have a full range if you use the pedal to control the
   pitch of the synth patches. I would have expected that all the line6
  gear used the same pedal spec. and certainly that all the "pro" range
   would want exactly the same pedal.
3) Reversing the toe-up heel-down won't really matter, as the unit is 
   programmable.
4) If you modify a vol/exp pedal, don't forget that sometimes the mechanism
    won't move the pot through it's full range.
5) the Boss FV-50L works perfectly . 
6) a standard expression pedal isn't wired correctly, but you could 
   put a mono jack on it and that should work.
