The snare strainer and snare butt are the two elements of a part of drum building hardware. As the name suggests the unit is used to apply tension to the snare wires that in turn press into the drum head creating the distinctive buzz sound.
One end of the unit is passive and simpy holds the snare wire retaining cord or tape. The other end is active and has mechanisms to;
- increase/decrease tension by small amounts usually by turning a small knob; and
- snap the entire unit on or off the drumhead, maintaining the tension when the snare is in the 'on' position
