First Plate Reverb


Back to the full Recordingography


EMT 140 is released by Elektromesstechnik (“Electrical Measuring Technology”) of Germany.  A large, thin metal sheet is caused to vibrate by a moving coil transducer placed near the center of the plate.  A bending wave propagates through the plate, reflecting off the edges, developing a complex pattern of reflections across the two dimensions of the plate.  Not measured in CPU usage or rack spaces, this plate reverb weights several hundred pounds and is almost 4 feet high by 8 feet long.



EMT 140S is released.  A second, strategically placed pick-up lets the same metal sheet go stereo.



You’ll want some help when you install it.
