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.
