so i just got the x-rack today and i'm a little confused. i have all of the bracketry, but as i set the head inside the rack, am i supposed to have the head resting on the bottom of the rack? or suspended in the middle of the rack? if i set it on the bottom, then the aluminum edge around the front of the rack is in the way of the knobs on the amp. if i set it halfway up, it seems like the weight of the unsupported back half of the amp would bend the mounting brackets. also, i though i remember someone saying that the stock handles on the front of the gk head could be left on if only turned another way..... someone please help me.
