The Gospel organ in the church at San Sebastián de Antequera (Málaga) was built by Tomás de Inés Ortega in 1803 inside an earlier case which was part of the organ Francisco Alejo Muñoz built in 1734. Tomás de Inés studied with Julián de la Orden, and had already worked under him earlier when de la Orden built and installed two organs in the Cathedral at Málaga between 1778-1783.
This instrument has 25 stops spread over two manuals and a Contra 16 for the pedal; this is the largest instrument Tomás de Inés built in the area around Málaga. It closely follows the layout of the organs in the Málaga Cathedral, although it is somewhat smaller. This is especially noticeable in the pipework and in its delicate voicing. Also noteworthy is the way he crafted the manuals and the action. But, over and above all else, look at the composition of the windchest for the two positives, a rückpositiv and an echo organ within the larger organ, both operated by a knee lever and notice the importance he gives to echo effects.
Although the pipework for the Great manual was badly damaged, the organ itself was not altered. It was restored in 2006-7, as part of a project called Andalucía Barroca 2007 sponsored by the Andalusian Governments Department of Culture.
