I used to own a DC-5 short head, which i sold and regret immensely. Looking for a new one and it seems like there are only combos around. I know a Mark IV combo can be rack-mounted, can a DC-5?
The DC-3 can be rack mounted, but not the DC-5.
The 5 is what Mesa calls the "Widebody"
The Mark IV's that can be rack mounted are the narrow style, not the widebody style.
