If the organ pipes are used, the two similar metal pipes are very good. They are simple to set up and adjust. Each is fitted with a collar at the end of which can be slid more or less off the end of the pipe to do the fine tuning required. Usually a tube connected to the low pressure air outlet is connected to the T-tube made of brass. Each branch from the T-tube goes to one of the organ pipes.
