Buzzy Jazz basses

[drneau]

Okay,

I've now tried three different Jazz basses...one with active electronics. They all exhibit the same symptoms:
- Bad buzz at home when I don't touch the strings.
- Quiet at home when I am touching the strings.
- Mild buzz at the store whether or not I'm touching the strings.

Obviously the problem is not just the bass.

I tried a new Schecter bass with humbuckers...slient as can be at home, whether or not I'm touching the strings.

So, there appears to be something about my house that the single-coil pickups of the Fender don't like.

My problem now: I LOVE the tone of the Jazz bass, but the buzz is unbearable when not touching the strings. What can I do? Is sheilding it going to give me a shot?

Thanks for any input!
