John Entwistle

John Alec Entwistle (9 October 1944 - 27 June 2002) was an English bass guitarist, songwriter, singer, and horn player, who was best known as the bass guitarist for the rock band The Who. His aggressive lead sound influenced rock bass players.

Entwistle's lead instrument approach used pentatonic lead lines, and a then-unusual trebly sound created by roundwound RotoSound steel bass strings. He had a collection of over 200 instruments by the time of his death, reflecting the different brands he used over his career: Fender and Rickenbacker basses in the 1960s, Alembic's basses in the 1970s, Warwick in the 1980s, and Status all-graphite basses in the 1990s.
