Updated by Bob Shoring, who gave this as the source of the information: Attend weekly concerts and the organists keep me updated on matters related to the organ.
The only tonal change to the organ since 1924 was the moving of the 8' Arch Clarion stop indoors after 2011. When built, was an outdoor stop, speaking on 30" wind. It was said that it could be heard from ships in the bay or even downtown San Francisco. That stop originally had 44 pipes. I understand that when it was moved indoors, they added pipes to complete the rank. It is enclosed in its own chamber, tightly enclosed to prevent the loud stop from overwhelming the audience. It is a very brilliant, heroic trumpet. Other than that, the organ's stop list and character is just as Mr. Skinner left it.
The console is of walnut and was designed by Marshall N. Giselman (information from the Fine Arts Museums of San Francisco).
Updated through online information from Bob Shoring. -- While organ has been mechanically restored, it has remained tonally unchanged from its 1924 installation. It's now in excellent condition and is played twice a week.
