This is my Conn 905 ran through nothing but Conn Pipe speakers. This is how they sold this organ (only 8-10 made) There is a Leslie in this vid but its not switched on until the second song. When I brought this organ home I re-hooked all the pipes up without the Leslie (sold it to recoupe acquisition costs) Sounded very good. Obviously there is a dual 15" bass cab to handle the pedal notes
