As the Crescendo Pedal is depressed, more and more stops and couplers are turned on until almost all are on. This is often referred to as "Full Organ" although it does not include the unified stops, nor a few of the regular stops and couplers. Even so, with the Crescendo pedal on Full Organ, there are over 100 stops active - most of the 122 regular stops, plus whatever unified stops and others not included in the crescendo mix that have been turned on by other means. When the initial renovation is complete, "full organ" will be produced by over 1300 watts of amplification - a rather imposing amount of sound. Also see the comments about the Sforzando Reverse Piston, located just to the right of the Crescendo Pedal.
