Drum kit accessories
Cases
Drummers who perform in concert venues will usually 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 typically have heavy-duty road cases that securely hold and protect the equipment during transport.
Drum microphones
Professional drummers may carry their drum microphones to performances to avoid situations where a venue has substandard equipment. Dynamic microphones, which can handle high sound pressure levels, are usually used for close-mic drums. In contrast, condenser mic's are used for overheads and room mic's. Some drummers with their own mic have a set of drum-mounted mic's, an approach that eliminates the need for mic stands and reduces set-up time.
Effects
Professional drummers may carry electronic effects they use on their drums. This can include noise gates that mute microphones below a threshold volume.
Plexiglas screen
In specific 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
You may use an insulation-style filling or foam in the bass drum to lessen the "ringing" sound.
Metronomes
Drummers may use Metronomes and beat counters to develop a steady rhythm when practising.
Mufflers
Drummers also use Drum mufflers to lessen the volume of drums during practice.
