He used an LH1000 with two HX810s on the Rust in Peace 20th Anniversary Tour. He has since moved onto using the Kilo amplifier. In early 2011, Jackson released a Dave Ellefson Concert and Kellybird signature model, both in 4-string and 5-string variants.<ref>{{cite web

}}</ref> According to providence website, Ellefson has used or is still using the Dual Bass Station. Ellefson formerly used Peavey amps and his Peavey Zodiac DE Scorpio 4-string signature bass. In the early days of Megadeth, Ellefson, along with [[Dave Mustaine]], primarily used [[B.C. Rich]] instruments, most notably Ironbird and Mockingbird basses, the latter of which he has still been known to periodically bring out on occasion.

Ellefson plays exclusively with a [[Plectrum|guitar pick]], as he is unable to perform in fingerstyle the fast tempos and palm-muting in many Megadeth songs. Ellefson shifted exclusively to pick playing since ''[[Peace Sells... but Who's Buying?]]'', after recording their debut effort with a mix of fingerstyle and playing with a pick.
