Either the Fender '62 Jazzmaster Electric Guitar (Olympic White Brown Shell Pickguard) or the Fender Classic Player Jazzmaster (Sunburst) Special Electric Guitar
I dig Firebirds with P90s. My fantasy 'Bird would combine features of the two transitional instruments illustrated in the A. R. Duchossoir book, "Gibson Electrics - The Classic Years". Reverse body, non-reverse headstock (like a Fender), P90s. I could probably live without the short Vibrola.
