    I just installed the Seymour Duncan Musicman replacement system (pickup and preamp) - Alnico p/up - in my Stingray. It was pretty easy to install. I love the sound. However, I've noticed that when I touch the pickup pole pieces with my finger (while not touching anything else) I hear a buzz. Any idea how to fix this? Is this common with Alnico pickups? Any help would be much appreciated.

    Thanks!!!!

    I also instaled the SD system in my SR and I don't recall having that problem. I'll check it when I get home this afternoon and I'll let you know, but it sounds like a grounding issue to me.

    keep groooovin'

    Thanks for your help. I have everything grounded according to instructions.

    -I have the control cavity and pickup cavity painted with shielding paint.

    -The pickguard is shielded with foil.

    -The bridge and volume pot ground are soldered to the input jack

    -The pickup ground is soldered to the volume pot

    I appreciate your assistance.

    Thanks,

    Phil

    Hi Phil,

    I just checked my bass and ther is no buzz at all when I touch the pole pieces. I have checked other convinations (touching strings at the same time, touching only the strings, touching the knobs,...) and it's dead silent (I tested it with the volume of my QSC poweer amp turned to ten).

    Check if you have the same problem with another amp and make sure that the amp is properly grounded too.

    let us know if you can fix it.

    keep groooovin'

    Is the shield making it to ground?

    yes, the shield is making it to ground. I have both cavities painted and the pickguard shielded with foil. I tried taking the bridge ground off of the jack and soldering it to the cavity. I'm still getting buzzing.
