Or a customer calls, saying the organ sounds out of tune, but it can't be, because the dealer said it doesn't go out of tune. Click here for a few photos of the job. Most electronic organ systems use several speakers in a variety of designs and configurations - all attempting to create a more realistic pipe sound. These complex systems also need regular maintenance. Grille cloth panels are another overlooked item.
All organs have moving parts and mechanical contacts, especially for all the keys.
All church organs have pedal claviers. Pedal pressure can be precisely adjusted so all pedals require the same amount. Spring tension changes with age and use. Many circuit boards have edge connectors to plug them into sockets. I see a lot of problems associated with corroded edge contacts .
