hey all! I’ve been gigging with my beloved reissue V4b for about 6 months now. My band has a day booked in the studio this week and I’ve decided to track this next single with just the balanced out feature on the head. My question is, does the head have to be connected to the cab for power distribution or can I bring just the head and no cab? And help is highly appreciated! Also: the V4b di is ONLY pre amp. It does NOT feed any signal from the power amp as well. Thanks!!
