Here's the deal. A sargeant in my squad is looking for a '68 EB0 bass. He got ripped off on ebay from a seller supposedly selling one. He says he wants that specific year but wants to only spend $1200.00USD. He's a few years behind the curve because '68's go for much more than that. I told you that to ask you this... are there many if any changes to the EB0 between, say '65 and '74? I know this is right in Tom's area of expertise but maybe there are some other SG bass buffs out there. I know some have the slotted peghead and some not but as far as neck shape, etc that would actually make a difference to a gigging bassist is the info I need.
