Actually, if the designer there would've just staggered the knobs to the left and right, you WOULD have ample room for fingers. Too much attention paid to electronics and NOT ergonomics is how you get unplayable modules. For example, my AE system uses those little marked-shaft pots, but they were designed with ample space so that you can get into through the patchcord (actually pinwires in the AE) snarl and the other controls around.
