I've read forum posts on the relative advantages of the head/toaster and the rack and I think I'm going to get the head.
I currently have my Axe-Fx on an On Stage Stands tilted amp stand. The Kemper head is wide enough to fit on it, but I notice it has feet. Does the Head sit level on the stand, or does the spacing of the feet cause the feet on one side to be on the rack bar, and the feet on the other off? Or can you remove the feet?
