Chrome hardware, '57 Classic & '57 Classic+
One or two piece back is strictly luck of the draw. You'd have to see a picture of the actual guitar's back if you're looking to buy.
I've seen a Tribute with a one piece back and that's uncommon for sure.
Mm I'd wondered if that might be the case regards the backs. Some look 1 piece ,some look 2, but I wondered if the one piece ones are just particularly well matched.
I know of a guitar coming up soon nearby,but yet to see it.
