Last night I noticed that my '73 Fender Jazz has not only the PUP moved back 1/4", but the actual bridge is also moved back equally (1/4"). Is that normal? So ultimately, the distance from the bridge back (where the string balls stop) to the bridge pickup on the '73 ends up being the same distance as that same space on the '96. The bases in question here are a '73 Jazz compared to a '96 MIA. That was a new discovery for me Just thought I'd share.
