    Hey everybody,
    the jack part of my Full Circle pickup rattles and nothing I've tried so far seems to help. Any ideas?

    If you're talking about the part the 1/4" cable plugs into, try some different cable brands; the male jack can vary ever so slightly in diameter.

    It's not the cable, because it rattles when there's no cable plugged in it.

    Is the nut tight?
  5. On both of my basses I removed the string clamp from the Full Circle jacks and tied the jacks to the tailpiece, through the g-string hole. This also makes it so the cable doesn't stick straight out from the string afterlengh, a bonus because I often had people step on my cable and yank the jack off the strings on tight stages! Might take care of your rattle, too.

    There is definitely a design problem with that clamp. It's easily detached in a variety of ways, usually by just trying to remove the cable from the jack. I tried it with my Ehrlund EAP and the BP-100 jack mount, and found it to be very unsatisfactory.

    Make sure the nut is tight and put a drop of Loctite on it; make sure the RCA connector is tight as well-I had to give mine a little squeeze to keep everything together. I use a George L cable w/ right angle connector on the pickup end.

    I dont trust Full Circles anymore after I had one EXPLODE on a gig the cover popped off taking out bridge-soundpost etc...its just a thin sheet of aluminum that does not posess the structural strength of a normai bridge adjuster...That being said i am sure that the majority of users have had no problem whatsoever..and they definitely sound fine ...mine had the cover where the bridge sits ---held on by one thread and a tiny spot of glue.new from factory.:eek:

    check your jack sleeve (the part that screws on and covers the solder connection)

    Thanks for the replies everyone!
    It's the clamp that's rattling and it's driving me crazy.
    tyb507, what did you use to tie the clamp to the tailpiece?

    You could probably stuff something inside each side of the clamp with the string (segment of a round cross-section toothpick?) and eliminate the rattling. I keep mine close to the tailpiece over the silk and there's no rattle whatsoever.
