Like the XK-Traditional, the Hammond XK-Professional System allows our single manual organ models XK-3 or XK-3c to be converted to a double-manual console-style organ without any modifications to the XK-3 or XK-3c. It happens without tools or technical experience. The organ separates into two parts plus the stand, and the stand collapses for easy transport. A “B-3” style 25-note pedal board and bench are available to match. When the XK Pro is assembled, it has the same “proportions” as a B-3.
