By "Cathedral" you are possibly meaning the Diocese Church of the area? Our Diocesan "Cathedral" is a rather large edifice and it does have a pipe organ, and that's about all that can be said about it. The last time I played it, the organ (25 odd ranks) was in need of lots of TLC as there were dead notes, non working stops, not to mention that the organ chamber (in the chancel area) was high up on the wall (no pipes showing whatsoever) trying to speak out of an enclosure opening about 6 feet square ... a typical "service instrument" installation with no thought to the organ ever being used for anything more than playing hymns and liturgies. The acoustics are what saves this organ - marble floors, no carpeting anywhere, high ceiling, very long nave ... about 3 to 4 seconds natural reverberation. Alas, the organ isn't used all that often - they primarily use Mariachi's and other ear piercing noise makers.
When I was vacationing in Sacramento a few months ago, I was looking specifically for a couple good pipe organs to see ... alas, found only the one (Presbyterian above) and a Lutheran church who's pipe organ was recently torn down and replaced with an electronic while being refurbished. The local "cathedral" there does have an organ, but it is not known whether it is pipe or electronic. Even at that, the Presbyterian church was doing contemporary rock (happy clappy) services the weekend that I so dearly wanted to hear the pipe organ played ... pitty ... real pitty that these great organs are being cast aside so that we can have the hairs on our heads parted in the middle and experience loss of hearing by age 40 with over amplified distorted noise.
