They don't really have to be related in any way (Vpot = VlFOoutput and most
likely not).  Put a voltmeter across it and turn the pot to the min and max.
Should give you an idea of what voltage is being used (typically they're
taken from the +12v or across the +-12v sources but its hard to say without
the schematic.  Yep you could use the pot as an attenuator and that's a
really good idea actually (put the jack as the input tothe divider instead
of whatever fixed voltage source is used - but then you'll always have to
use a CV unless you put a little switch in as well to switch between CV and
normal voltage source - or normalize it but that's another issue entirely
:-), but first figure out the voltage etc.
