Paweł Mąciwoda (Polish pronunciation: [ˈpavɛw mɔ̃t͡ɕiˈvɔda]; born on February 20, 1967) is a Polish bass guitarist who joined the Scorpions in 2003, and became an official member on January 10, 2004.
Born in Wieliczka, Poland, Mąciwoda began playing bass guitar semi-professionally at the age of 15 with his father's encouragement. His young age on the rock and roll circuit earned him the nickname "Baby", but within a few years Mąciwoda was touring Europe with a jazz fusion band called the Little Egoists, and for overlapping periods of time performed as a member of the avant-garde rock bands Düpą and Püdelsi, both based in Kraków. At about the same time he also released a solo album entitled Radio Wieliczka. His other band credits during his early years included the popular jazz-rock band Walk Away, headed by the world-famous violinist Michał Urbaniak and lead vocalist Urszula Dudziak, with whom he recorded the album Magic Lady.
As of 2011, Paweł has been collaborating with friend and fellow musician Efrem Wilder in the outfit Stirwater. The name Stirwater is derived from the English translation of Paweł's last name "Mąciwoda".
