 During the auditory tests, sustained tones and excerpts from musical works were played on the electric and pipe organs while a group of musicians and laymen attempted to distinguish between the instruments.While attorneys for Hammond argued that the test listeners were wrong or guessed nearly half the time, witnesses for the FTC claimed that Hammond employees had unfairly manipulated the Skinner organ to sound more like the Hammond.In 1938, the FTC ordered Hammond to "cease and desist" a number of advertising claims, including that its instrument was equivalent to a $10,000 pipe organ.
