===Doktor Avalanche===
The original incarnation of Doktor Avalanche was a [[Boss Corporation|BOSS]] DR-55 ("Doctor Rhythm"); the Doktor was later replaced by a [[Roland TR-606]], soon followed by a [[TR-808]], and, briefly, a [[TR-909]]. On one album, ''[[First and Last and Always]]'', an [[Oberheim DMX]] bore the Doktor name.<ref name="da">{{cite web |url=http://www.the-sisters-of-mercy.com/tech/doktors.htm |title=Biography of Doktor Avalanche |publisher=The-sisters-of-mercy.com |access-date=21 February 2012 |archive-date=24 November 2010 |archive-url=https://web.archive.org/web/20101124063125/http://www.the-sisters-of-mercy.com/tech/doktors.htm |url-status=live }}</ref>

With increased financial resources from sale of the album, the Doktor was upgraded to a [[Yamaha Corporation|Yamaha]] RX5, and subsequently reinforced by [[Akai]] S900 and [[Akai S1000|S1000]] samplers. An Akai S3200 has been used as studio equipment. Soon after, the first [[Digital data|digital]] Doktor appeared in the form of a set of [[Compaq]] portable PCs, which had to be scrapped when it became impossible to maintain them because of a lack of [[spare part]]s.<ref name="da" />

In recent years the "Digital Doktor" has been moved to a custom-built laptop designed by Eldritch and constructed by an English military software and hardware company. For a time there was some division in the band whether or not the Doktor should be moved to a [[Mac (computer)|Mac]] running [[Logic Pro|Logic]] or remain as is.<ref name="da" />

In a 2011 interview with a New Zealand radio station, Eldritch said Doktor Avalanche was now a [[MacBook Pro]] laptop running [[Steinberg Cubase]].

Doktor Avalanche also "runs" the on-line [[advice column]] on the group's website.<ref>{{cite web|url=http://www.the-sisters-of-mercy.com/misc/deardok.htm |title=Dear Doktor |publisher=The-sisters-of-mercy.com |access-date=21 February 2012}}</ref>
