Noisey MM - Shield it or take it back?

    Hi Guys,

    Bought a Fender Marcus Miller 4 weeks ago - I love it, but it's
    got some horrible ground noise - ie, the kind of noise that
    goes away when you touch the strings. Granted, I have crappy
    2-prong AC in my house, none of my other instruments make this noise.

    So do you think shielding the cavity will cure this problem?
    Or should I take it back and get something different? I've
    only got a couple of more days till my 30 day return is up,
    so I need to decide soon.

    The only other instrument in my price range that I'm interested in is maybe a
    standard MIA Fender Jazz, but I'm not confident that
    will be much better. Of course I'd love a Sad. Metro MV4 which
    I'm positive will be better, but I can't afford that. Sigh.

    I want to keep the MM, but I absolutely must get rid of the
    ground noise.

    Do your other instruments have humbuckers? Does the hum go away with both pickups on full?

    Yes, the other instrument have HB's, but I can split the coils and put them in single coil mode - still quiet.

    The noise does not go away when both pickups are on full. The noise
    isn't too bad in passive mode with the vol. up 50%, over 50% vol. and in active mode, or with tone controls up, noise-o-rama.

    So I decided to keep the bass. After recently playing out,
    I decided the buzz wasn't loud enough to notice in a live setting.

    In the studio, the buzz is only bad when I take my hand
    off the strings. Since I play with a pick, this can be bothersome
    when I play open strings.

    Solution. Since I rest my palm on the pickup cover when I play,
    I connected a wire between the bridge and the pickup cover.
    This has the effect of always touching the strings when I play,
    so I don't get any static when I play the open notes.

    Eventually I'll change the pickups to HB's and shield the bass.
    I believe most of the noise derives from the cheap ass preamp,
    so that may need to be upgraded to a bartolini, sadowsky,
    or j-retro pre. Or, alternatively, just trade the MM in at that
    point to a lakland or sadowsky.

    For now, the bass is great. Though a little on the heavy side
    (10.5lbs) and the afformentioned noise, it's really fun to play
    and sounds great.
