The First Lutheran Church organ is a charming small two manual tracker instrument built by the Werner Bosch Co. of Germany, in 1965. It was originally a practice instrument at Christ College in Oakland (now with Concordia University, Irvine), and was installed at First Lutheran in September of 1973.
Interestingly, while the manuals have mechanical action (meaning the connection between the keyboards and the valves in the chests that the pipes sit on is all mechanical) the pedal is electric action (meaning that when a pedal key is played an electrical contact is made and a magnet under the corresponding pipe opens the valve allowing air into the pipe wired to switches, running on 12 volt DC current).
The instrument is housed in a free standing case made of German oak. The keyboard naturals are capped in Ebony and the sharp keys have Boxwood caps. The front pipes in the middle of the case are 70% tin, those inside the case 60%, except for the Holzgedackt (wood stopped flute), which is made of Raminwood from Malaya.
