Updated through online information from Timothy Tikker. -- The brass horizontal reed is named "Trompeta real" (not "Trumpeta" as per the cathedral website). Metal pipes are 55% tin, except mixtures and single-rank stops above 2' pitch which are 70% tin, and the Swell 16 Contrafagotto, Pedal 16' Dulciana, 32' Contrabombarde and 16' Bombarde, which are tin-plated zinc. The Swell 16' Bourdon is unified with the 8'; this rank has mahogany pipes, as does the Pedal 16' Subbass. The Swell Flauto dolce, Choir Erzaehler and Positiv Sesquialtera II all begin at tenor C. The Swell 16' Contrafagotto is half-length, as are the lowest eight notes of the Pedal 32' Contrabombarde. The Positiv 16' Dulzian and 4' Musette are quarter-length. Changes were made in the Pedal a few years after installation: the 32' Resultant was replaced with an electronic Contra Bourdon; a 16' electronic Principal was added, and the original 16' Principal was relabeled "Dulciana."
The organ is on the right side on a concrete pedestal. The console is on the floor.
