Ultrasonic pickups are a brand of magnetic guitar pickups developed and produced by Bill Lawrence in Germany. Ultrasonic pickups are passive pickups designed to have a very flat frequency response curve, without the mid hump delivered by most guitar pickups. Ultrasonic pickups were featured on some guitars in the Artfield and Maxxas series.

The pickups were produced for only a brief period (maybe six months) in the late 1980s.
