John Entwistle’s “Explorer-Bird” Not only did The Who’s groundbreaking bassist redefine the role of the bass guitar in rock, he was also a trendsetter in what gear bassists used. “The Ox” used this custom made bass, which features a maple Fender P-Bass neck grafted on to a Gibson-style Explorer body, in the late ‘70s, most notably in the video for “Who Are You.” Following his death it was bought at auction for £12,000 in 2003 by Widespread Panic bassist Dave Schools.
