I am sorry to call them this, but the funmakers were just glorified toys. They were made from themid 60's to most of the 70's with many different models. They were far from some of the nice spinet and home organs as well as church organs that Wurlitzer made. All of the various organ companies made some awful junk during that time frame. When it was discoverd a small keyboard could do as much has those glorified toys the organ market began it downward plunge.
