As a bonus, if you score an Apollo, among the many world class plugins you have access to is IMO, the ONLY Guitar amp emulation that can rival FAS, the brilliant Fender Tweed Deluxe created by Fractal buddy and contributor James Santiago, now tone guru at UA........Apollo Twin USB on WIndows user here. Love it.
I think the only drawback I'm feeling with the Duet is that breakout cable. Seems likely to break. Digging the fact that the babyface has XLR outs as well.
