Can't tell if Cliff owned this or not, since he didn't purchase his Spoiler from us. All I can really tell you is about the bass itself:
 
body: solid Koa
neck: 3-piece Maple
scale: 32 medium
fingerboard: Ebony
inlays: Pearloid (plastic) ovals
finish: Black
originally made for: Guitar Center, Hollywood
birthday: April 21, 1983
 
There's no ownership or repair record in the paper file.
