    My only two basses are a CIJ Jaguar and a Squier P-Bass.

    I recently put them neck to neck and they are the exact same thickness. Could it be that the P-Bass neck was shaved down a little too much in the factory? I know basses have slight variations and have even heard of a P-Bass neck that is thinner than normal.

    And what it the difference again? Its from 1.75in to 1.5in, P to J?

    precision necks will be anywhere from 1.75" to 1.6" wide at the nut
    also some precision necks will be the jazz width of 1.5" at the nut

    there will be more variation between necks in their front to back thickness
    and i think either neck can be thick or thin front to back...
  3. I am no expert but I've been led to believe that P's *usually* are 1 3/4" wide at the nut- referred to as a *C* neck- but there are also 1 5/8" nut widths(*B*)as well as *A* @ 1 1/2". Jazzes, IME, are 1 1/2" although there are very slight variations. I think the Geddy Lee neck is a bit slimmer than typical Jazz width.

    Edit: Slow typist- what jmpiwonka said. :)
  4. Generally, it was older P-basses (50s-70s? I think) had the 1 3/4" nut which then changed to 1 5/8", which is the current nut width now, except for maybe reissues of older models, and those special models that have been fitted with Jazz necks . The Jazz has always been 1 1/2" (AFAIK, that is).

    i think most of the 70s precisions were b necks.
    my '77 is a B neck.

    My 71 is a B 1.625
    My 74 is an A 1.500
    I had a 62 reissue that was a C 1.750=too wide for me.

    The body they are attached to
  8. It's not about the thickness, it's about the width.

    Yea I meant the width, not the thickness. And I measured more carefully and the Precision neck is SLIGHTLY wider. It's a very small difference, and I couldn't really tell holding them neck to neck.

    I am assuming the P-bass was just slightly thinner than factory standard.
