MOTM

Ok, this is slightly off topic, but...
As I mentioned once before, I took the mod/bend wheel assy. from a junk
Polysix
& made it an out board controller for my MOTM--I feed voltage into it from
the 800 EG
& send it out to wherever.
My question:  The Polysix has a Bend Intensity pot on the panel that
controls how strong a
pitchbend you get.  What I'm trying to figure out is if I can make this same
principle work on
my little mod controller.  Would the pot need to be wired on the ins or the
out?  Is there
a need for additional circuitry?
I'm sure this would be fairly simple to figure out if I understood
electronics better, but
I don't, so I'm throwing it to the panel of experts in the hope that they
can guide me out
of the darkness.

Thanks
