Okay, so what's REALLY the difference between the Dean Edge 4 and the Dean Edge Q4? Besides $110? I'm reading that the Dean Edge Q4 doesn't have active pickups, it has passive EMGs and an active preamp. So I have two questions: On the Q4, if the battery dies in your active preamp, will the pickups still function and allow you to play just without the preamp (as in, if your battery dies midshow and you have no replacement, are you screwed?) and then, what pickups are on the regular Dean Edge 4? The threads on here cant seem to agree on whether they are EMGs or not.
