So the bridge string spacing of the originals was narrower than modern deluxes and/or the custom and thinline models of that era? I've replied to Fender for more general information on the bridge string spacing of the AV II '73 Deluxe specifically.
Yes. It was 2 1/16”. I don’t think that changed over the run as Fender appeared to keep using the same block saddles. The reissues to my knowledge have never quite Replicated the original spec… Normal HBs in big covers vs WRHBs, trapeze F tuners vs sealed 2-prong, normal bridge and nut width, 12” rather than 9.5” radius… This one is at least getting more right. But then I’m not 100% sure whether any measurements changed by ‘81.
