If the only bass that Jet had at one point was the Framus, which then got broken, then somebody must have procured the sunburst Precision for him very soon after, as he evidently had no instrument at all and they had ongoing gigs..who knows? It may have been a loan from JMI, or maybe the management bought it for him. Then maybe their management did the JMI deal for the Vox amps and the matching red instuments..
Thinking about it, at one time or other, in the group or solo, they used almost every available model of Fender guitar and bass!
I can think of.....Strats(Hank and Bruce, and Jet years later), Jazzmaster(Bruce), Jaguar (Jet) , Tele (Bruce) Precisions (Jet, Lic), Jazz bass (Lic and John) and Bass VI (Jet and later, Hank...)
There were also various Gibson and Martin acoustics(one Martin with a built-in DeArmond pickup- Bruce), and electric hollowbody Gretsches (Hank and Bruce, and Jet on the Diamonds recording (tuned down to D)
Then the Burns guitars, basses and 12 string guitar...
How am I doing so far, JimN??
