For the "small" solo reed, I used the Trumpet of the Great played on the Choir through the use of the "Great Reeds on Choir" drawknob, which makes any Great reed drawn play on the Choir but NOT on the Great. You can also play the Great reeds on the Solo with a similar stop knob.
The big Tuba seems to have more of a "ring" to it.
The Pedal reeds here do not seem to have the same thunder as they do at Hereford.
The full organ, including the Solo Tuba coupled in, does not seem to be as big here, but that could be that the recording was made farther away than at Hereford.
Notice that the full Swell sounds VERY far away on this one.
