Drum kit accessories
Drummers who perform in concert venues often have a variety of equipment cases to transport the drums, cymbals and hardware. Performers who play local gigs may only have relatively inexpensive padded cloth bags or thin plastic cases. Professional touring drummers who have to ship their drums will typically have heavy-duty road cases that will securely hold and protect the equipment during transport.
Professional drummers may carry their own drum microphones with them to performances to avoid having situations where a venue has sub standard equipment. Dynamic microphones, which can handle high sound pressure levels, are usually used to close-mic drums while condenser mic's are used for overheads and room mic. Some drummers who have their own mic have a set of drum-mounted mic's, an approach which eliminates the need for mic stands and reduces set-up time.
Professional drummers may carry electronic effects they use on their drums. This can include noise gates that mute microphones below a threshold volume.
In certain settings, such as country music clubs or churches, the drummer may use a Plexiglas screen to dampen the onstage volume of the drums.
Mats / Carpets
Drummers playing in different venues may carry carpets or mats to prevent the bass drum from slipping on a wooden floor.
Insulated filling / foam
An insulation-style filling or foam may be used in the bass drum to lessen the "ringing" sound.
When practising, Drummers may use Metronomes and beat counters to develop a steady rhythm.
Drummers also use Drum mufflers to lessen the volume of drums during practicing.
