    More questions about this bass:
    First of all, is it normal for a MIA 62 reissue to hum like nobody's business? I don't think the pickups are phase cancelling because the buzzing gets WORSE with both pickups on. Any clues how to fix this? It has weird grounding where the wires are soldered to a metal thing at the bottom of the cavity. Does that have to do with the weird strip going from the bridge to the bridge pickup?

    Also, i checked out the neck pocket and it says "SANTIAGO" on it. Der, I'm pretty sure none of fender's instruments come from Chile, so does anyone know what this means?

    are you by any lights? or in front of the computer?
    the bass is humcanceling when both pups are full on.
    the strip is the ground.
    and maybe thats the name of the person that assembled it?
    or maybe the guys at fender named it.

    Sounds like you got one wrong pickup.
    MIA Fender pickups have pickups with differing polarity, so they are humcancelling when they're both on.

    The grounding seems to be ok.

    [EDIT] I'm not sure if the 62 reissues are humcancelling - anyone?

    Except for the earlier MIM versions, the two pickups in the Jazz have been humcancelling when both are on full pretty much since it was introduced. If the Jazz has humcancelling pickups in '62, I can't imagine the reissues don't.

    So, your bass should have less hum, not more, with both pickups on full. With the grounding strip to the bridge in place, it would usually have less hum when you're touching the strings than when you're not, too. Assuming that the pickusp haven't been swapped out or something, if it's not working that way, then you've probably got a grounding connection that's come loose somewhere.

    However, I don't know the wiring of a reissue Jazz by heart (though I'm sure somebody here does!) so I couldn't tell you what should be going where.

    Thanks a lot guys, i really appreciate all of this info! I'll ask my local guy about the grounding thing. It definitely hums more when my fingers aren't on the strings. thanks again!
  6. My CIJ Geddy Lee Jazz supposedly has MIA '62 Vintage Reissue pickups, and they are MOST DEFINITELY hum-cancleling! Wow.
