I used to work in radio, and I have always been fascinated with audio recording and production. On a tour of RCA Studio B in Nashville, I saw two "Mojo Makers" in a rack of processing equipment. They are obviously custom-built, and I have been unable to discover what these devices do. They both have a Gain control and a meter switch which has positions of Off, V1, V2, V3, V4, V5 and V6. The meter face says "Test," and has a range from 0 to 50. The top unit has two other controls. One is unlabeled; the other is unreadable. Does anyone know what these "Mojo Makers" are and how they were used?
