Motograter is an American nu metal band. They are best known for their homemade instrument the "motograter" - designed with industrial cable and guitar pieces that creates a very deep bass sound. The "motograter" instrument originally took place of the original bass guitar but now accompanies it. The band is also known for painting themselves in a tribal style body paint for concerts. Motograter was founded in San Antonio, Texas in 1995 by Bruce "Grater" Butler playing the Motograter, Joey "Smur" Krzywonski on percussion, Chris "Crispy" Binns on drums, and Zak "The Waz" Ward on vocals.
