jan 1, 1975 - Plate reverb

Description:

In 1957 the German company EMT (Elektromesstecknik) produced the EMT 140 a 600-pound (270 kg) model popular in recording studios, contributing to many hit records such as Beatles and Pink Floyd albums recorded at Abbey Road Studios in the 1960s,  
A plate reverb system uses an electromechanical transducer, similar to the driver in a loudspeaker, to create vibrations in a large plate of sheet metal. The plate’s motion is picked up by one or more contact microphones whose output is an audio signal which may be added to the original sound/signal.
