The electronics on the slothead EB-0 are the same as the earlier ones.
The early ones were, but not he later ones; bit of a mishmash in the middle as they tried things. As usual for Gibson, not that cut and dry.
As for value, I'm going by what has actually sold on Reverb according to their price guide. Also, I question whether any guitar or bass with a repaired neck break should be listed as Good condition by Reverb's standards: "Good condition includes items that are in fine working order but have some visual imperfections here and there." IMHO, a repaired headstock break is worse than that. At least the seller is upfront about it.
As was I. None of their stuff says any era is worth a penny less than 1k, so free shipping AND 15% off, in addition to this being the bottom of the valuation to start with is a deal, if not a huge one, assuming no breaks which I missed in the initial excitement which I have already admitted and apologized for. I woulda looked closer if I was actually considering buying it myself. Totally agree about the condition thing - I'm just gonna blame that for not noticing the blurb about repairs ;P
Wasn't '65 the year they phased out nickel? Not to be picky, but..😃
I always look for pre- 66 basses, and see pre- 66 as series 1. But that is more of a personal preference; as they changed the neck heel in 66 and started to make the narrow necks, which I don't care much for. Interestingly (to some) you can find 66 models with the new heel design but with the 'old' wide neck/full nut width.
Yes (I said pre-66; same thing).
My 65 (pot codes + nickel + originally a bar bridge, now long gone) has a skinny ass neck; original heel style. I always found the necks got fatter later, rather than earlier (esp 70s ones; much bigger). I'm sure they weren't always very consistent though, especially in transition periods.
