Marvin Isley's Stage-Used Fender Bass Guitar. This dark red Fender Precision Special four-string electric bass was owned and used onstage by the legendary bass guitarist and Rock and Roll Hall of Fame inductee. Isley became a full-fledged member of the Isley Brothers in 1972, and made his debut with the family group on their chart-topping LP 3+3. The guitar is in Fine to Very Fine condition with moderate chipping and wear to the finish on all sides of the guitar, and is accompanied by a b&w 8" x 10" publicity photo of Isley and a hardshell carrying case in Fine condition with wear from regular use.
