Chuck Rainey's bass in Steely Dan episode of Classic Albums?

I think this came up in another thread, and it was identified as a Heartfield.

Heartfield by Fender DR-5 Blueburst 5-String Bass Made in Japan

The color in this one is wrong, but the headstock seems to be a match.

 

Otherwise, it's been identified as a Washburn prototype that Chuck was helping design at the time.

+1. I posed the question to Chuck directly many years ago via e-mail, and he confirmed the same. The prototype never progressed into production.

 

Thanks for the correction!

 

Nah, not a Heartfield - look closer at the tuner layout. The D string tuner position. Not the same.
