I looked at the website where you got your neck and didn't see a 59? What's it like in thickness compared to a gibson and how is the quality? I am always on the lookout for a good neck maker.
I checked Edenhaus (http://www.edenhaus.com/Necks.htm) out also ... maybe this one was a special order (Sean DID say it was a CUSTOM 59) ... but any solid info concerning the provenance of any of the Rataecaster's bits will have to come from Sean himself when he returns from his hols.
Quality-wise it seems absolutely immaculate: very thick slab of luxurious-looking Brazilian rosewood (no veneer here!) over lightly figured maple tinted just right -- it neither looks like it was just attacked by a vampire, nor like it'd been on a spray-tan binge with a Z-list celeb.
Shape-wise, as I said earlier ... it's somewhere in between my '63 and the Jeff Beck. I'm insufficiently familiar with all the different Les Paul variant necks to answer in more detail with any authority. Apparently Edenhaus are 'licensed by Fender' to use the headstock shape and everything, which suggests that the Big F has considerable faith in their craftsmanship and QC. Hell, for all I know they supply necks to the Custom Shop ...
This one arrived with a Fender logo, though I'd actually been hoping for one of Sean's personalised 'Fecker Partsocaster' labels. After all, any ****************er can have a Fender, but only a real fecker has a Fecker.
