I think my (2nd) favorite model is the "concert" model (RT-3), because of the AGO pedalboard, and the solo pedal unit. I played a concert on one of these, and it was a great success. We had to rent a Leslie though, because the 2 Hammond tone cabinets that the church had, didn't really sound that good. The sound of the organ was 'dead', but when we hooked up the Leslie, and put the tremolo on slow (chorale), it really sounded great, as the sounds was now 'alive'. If a church has a Leslie speaker on their Hammond, it can sound pretty good.........
