Hammond XK5 Model A3 Lower ManualThe A 3 lower manual uses the same key bed and multi contact system as the XK 5. It features the same high quality cabinetry, with vertically extended side panels designed to cradle your XK 5. Remove the existing side panels from the main unit (a quick and simple operation), slide it into place, and you have an integrated dual manual rig with a seamless appearance. Please note, if you plan on attaching a Hammond XK 5 to the Hammond Model A 3 spindle
