===Extended kits===
[[File:OutsideBRX-15.JPG|right|thumb|200px | A seven-piece kit typically used for [[heavy metal music|heavy metal]], [[jazz fusion]], and [[progressive rock]], consisting of double bass drums, two-floor toms, and an extended set of cymbals (three crashes with [[splash cymbal|splash]] and [[China cymbal|China-type]]).]]

Common extensions beyond the standard configurations include:
* [[Effects cymbal]]s, particularly [[splash cymbal]]s and [[china cymbal]]s
* [[Double bass drum]]s or a [[double bass pedal]] are standard for some genres, particularly heavy metal music
* Extra hanging or [[rack tom]]s
* Extra crash cymbals
* A [[crash/ride cymbal]], in addition to the main ride cymbal
* A second floor tom, either larger or smaller than the first
* One or more [[octoban]]s, or a pair of [[timbales]]
* A second pair of hi-hats mounted as [[cable hats]] or [[x-hats]]
* [[Cymbal stack]]s
* Different types of [[gong]]s
* Multiple ride cymbals; a [[sizzle cymbal]], thinner and larger than the main ride, was once common as a second ride or crash/ride, even in a four-piece kit, but is now less so (jazz drummers, however, may still have two or more ride cymbals, even as part of a small kit).
* An additional electronic [[sound module]] or [[music sequencer|sequencer]]

See also [[#Other acoustic instruments|other acoustic instruments]] above. Another versatile extension becoming increasingly common is the use of some [[#Electronic drums|electronic drums]] in a mainly acoustic kit.

Less common extensions found particularly, but not exclusively, in very large kits, include:
* Multiple snare drums, usually in the form of side snares. A side snare is usually positioned to the left of the drummer (opposite the floor toms and to the left of the hi hat). Side snares are used, similarly to effects cymbals, when an additional and different sound is required. Generally only one side snare is used in a kit, if any at all.
* Multiple bass drums beyond the double bass drum setup
* [[Gong drum]]s (single-headed bass drums, played with sticks or mallets)
* Sets of [[gong]]s, tuned or untuned
* Sound effects such as a [[thunder sheet]]
* One or more [[crotales]]
* Instruments "borrowed" from [[orchestral percussion]], such as [[timpani]]
* Instruments "borrowed" from [[marching band]] percussion, such as the tuned bass drums used in the [[drumline]]
