Just out of curiosity . . . Could you substitute other pickups for the ones that come in the Game Changer and still be able use all the coil configurations?
You can replace TGC pickups with (almost) any passive guitar pickup.
I say, "almost" because it is hard to know the specifications for every single pickup in the world made by other manufacturers, and "passive," because active pickups tend to have preamps built in that could potential overload the input of The Game Changer.
