Weird, I know I posted this response yesterday, but it seems to have disappeared. That or I'm just out of it.
Anyway, this part of the description makes absolutely no sense. Not in the guitar world, the recording studio world, the world of the musician's union, or the physical world in which we all live:
"the guitar [...] was jury-rigged with four pickups wired into extra jacks that would each plug into a separate channel on the recording console. With the Fender modded this way, the session player could collect four times union scale for playing four slightly different versions of the same guitar solo."
And neither does this:
"Because of its provenance, the guitar also became seriously valuable, with reported insurance estimates ranging from $1,000,000 to $5,000,000."
I don't doubt it would go for a million, but not a lot more. Springsteen is not famous for being a guitar player, and it's typically the guitars of people known as guitar players (you know, the ones who do all the fiddly bits in the songs) that fetch those 6 and (rarely) 7 figure prices.
