DS201
Effects by Drawmer
The Drawmer DS201 is a dual channel noise gate introduced by the British company Drawmer in 1982. It was the first gate to offer frequency conscious gating, using variable high and low pass filters on the side chain so it triggers only on a chosen part of the signal, and it became the studio standard for tightening drums and stripping out unwanted noise.
