That's the Midnight Blue 4003S/5FL that is featured in the Second Edition of the book! A vendor a few years ago had this one and a Red one (not Fireglo, but Red). The pair could be the sum total of 4003S/5FL made!?
I had never heard of them until Chris P. mentioned them years ago
Great looking basses, but I've read mixed reviews of the tone. Geddy Lee played one for one song on the final RUSH tour, and it was easily the least impressive of the 19 or so basses he played that night. Kind of "tubby" sounding.
Jeff, you know that Gil owns one too... a '67 Fireglo. Four years ago I had the honour of shunting its cap.
