I edited my post, but yeah, you'd kind of have to. In fact, you'd mostly just be using the Master to undo the preamp gain. It actually looks to me like this box is basically intended for pounding the preamp into saturation and the cranking it back down to reasonable levels.
Sure, but you'd start it at the 0 mark, set the gain normally, then start raising the gain for saturation and lowering the master to keep the record level correct. Starting with the master nearly all the way down is nuts.
