    I have recently purchased a set of Dimarzio model j, jazz bass pickups, and wonder if shielding is necessary???

    First off, let me say that I have searched the posts for shielding and have found a great amount of conflicting information...

    I plan on installing these pickups with a traditional j bass vol+vol+tone control plate and pots...

    I have seen the schematics and have a hard time understanding the grounding deal...

    If the bridge is grounded, do you still need the shielding???

    I have read Hyscock's book on electrickery, but have a difficult time assimilating his excellent info for bass...

    HELP!!!

    I'm waiting for some shielding tape from Stewart-McDonald for my 2 unshielded basses. I have a Carvin LB20 (with the DiMarzio Model Js, by the way) that has a thoroughly shielded control cavity, and it is very quiet. Then there's the Squier II P bass, which is utterly unshielded and very noisy, and my favorite POS, newly fitted with Select humbuckers, which is sort of noisy. Those will both get the foil treatment, and I will try grounding the shield to the electronics. I didn't look to see if the Carvin's shield was grounded when I was soldering up the new pickups. In any case, it's easy enough to try it both ways.

    Good luck : } - It makes a huge difference on any bass. I hope you aren't one of those guys that will use old tin foil from the-aliens-are-reading-my-thoughts hats, hershey kisses and candybars and gumwrappers just to save a dime. The best prices I've found on high-quality foil with conductive adhesive backing are on Carvin's site, and it's the easiest to deal with.

    Of course not! I'm still wearing my "aliens-are-reading-my-thoughts" hat: I can't afford to take a chance with using the foil for my basses.

    Wise choice.

    nope, not planning on using juicy fruit wrappers...although I did consider the dentine wrappers before they moved to paper...
    I bought a big old sheet of sticky back copper shielding for 7$from some guy in New Orleans...
    Heres hoping the mail is back up and running down there...
