Powerful, yes; smooth, yes; versatile, yes. But there was an unexpected phenomenon (N.B. this gets pretty technical, so you can skip it and go to the other images below):
“At one point I played a solo line using a combination starting at 8′, climbing through all the mutations from 6 2/5′, 5 1/3′, 4 4/7′, elevenths at every octave (that’s sounding an “F” when one plays a “C” key!), right on up through the highest septiemes, nones, and octaves (including 1 1/7′, 8/11′, 4/5′, 8/9, 1/2′ 1/3′, 1/4′ and others!) .
HERE’S THE THING
When the melody descended down to the lowest keys, there was a clearly audible resultant of 16′ in the tenor range that increased to a 32′ resultant in the lowest octave. Remember, the lowest pitched stop I had drawn was at 8′!
I drew the combination to hear the “weirdness” of all those mutations and as I played lower, James W. Martin, shop apprentice, pointed out that if I went even lower we’d hear this phenomenon. Thanks to him for suggesting it; it did not disappoint.”

Not that I was aiming for this goal, but I have now played the three largest organs in the world:
