Now known as an "oil can delay," this delay unit consisted of a tuna-can-shaped drum filled with oil, driven by a rotating belt, and a special disk onto which the audio signal "charge" was written and read by a rubber wiper "head." The playback speed was directly linked to the speed of the drums, and the oil acted as a protective layer to hold the signal's electron "charge," creating a unique echo effect that also contained elements of vibrato and slapback delay. The 3 Series Oil Can Delay is a simple and faithful homage to this classic unit.
