Drone Mask is one of the simpler masks in that the mask seals around the face and is then directly tied to a large 4″ diameter steel reinforced tube. At the end of there is a microphone to pick up the waveforms as they find their way to the end. The tube has natural reverb and bass tone characteristics, perfect for long low drones of the voice. By moving the tube and holding against different surfaces, different muting and muffling effects are achieved.
