​Rack kit for Golden Age Project red and black 1/2 rack units.

You can mix and match our black and red half rack units, building two channel versions of the COMP-3A and COMP-2A or perhaps one of each?
Or combine one black unit with two red units, perhaps one PRE-73 MKIII, a EQ-81 and a COMP-2A? That would give you a terrific vintage style channel strip!
