As some of you may have seen, I am putting together an American Design Experience bass. I am debating the merrits of spending $200 more for a 1964 AVRI Jazz neck or builidng a modern bass with the American Standard Jazz neck. (I am putting it on a Precision body). I am familar with and comfortable on the American Standard neck, but am trying to figure out why the 1964 is $200 more? I know the radius is 9.5" on the Standard and 7.25" on the AVRI but I'm really not sure how much impact that has (or how to describe it). Any experience you can share would be cool. Thanks!
