I'm in the market for a 70's Jazz. I came across a '75 (not a reissue) on a dealer's website. The picture shows it as having a 4 bolt neck. I love Fenders, but I have to admit I'm not an expert in their history. All the '75s I've seen (including the RI's) have had a 3 bolt neck. The dealer states that the potentiometers are dated 1974 and the neck plate SN puts it around a '75 (sn 628620). Has anyone ever come across a 4 bolt '75? I'd hate to call the dealer like some know-it-all and demand he take the neck apart when this is a common occurance. What do you think? ...also, if anyone has a 70's Jazz they're looking to sell...I am in the market. I do have a $1700 budget. My first choice is a natural with a rosewood neck, but I'll consider almost anything (no RI's please). Thanks for your help!!
