The 860 is a single channel Leslie with solid-state amplifiers in a Pro-Line portable cabinet.

This model was designed to be used with a combo preamp for portable organs and keyboards and was marketed on the basis that one would use several on stage – “add as many as you need to give you the power you need for any performance… anywhere.”
