Costello started the sessions for his first album, "My Aim Is True", playing a new Telecaster that a drummer friend who worked for Fender had gotten for him with a company discount in California.
Back in the UK, Costello walked past a shop window that had a Jazzmaster in it. Says Costello: "I'd never seen one before; it kinda looked like a Strat someone had cut a bit off. I didn't even know the guitar existed."
So he traded in his new Tele for the used Jazzmaster.
Costello's new guitar came with a DIY refinish, a "home furniture varnish like you would have on your auntie's footstool."
Later he had it refinished in a "not entirely attractive grey finish and put my name up the neck 'cos I was always into country and western-style guitar gimmicks. And I figured no one would nick it then, it'd be useless to them."
