As you turn the 'A' knob, not only do you alter the gain, but at it's 
centre point, the gain actually changes sign. Whilst this is 
relatively easy to do with the pot and op amp configuration used in 
the module, doing it with voltage control (especially the changing 
sign bit) is probably a considerably more complicated proposition 
altogether. Thus from what I know of the module, and with my 
understanding, I think a 'simple' mod is probably not possible.
