It doesn't go away when I touch the strings, which again, makes me think it's RF and not grounding. Does that sound right?
Here are some other facts about my situation:
* In other locations the bass is pretty near dead quiet
* Brand new battery didn't help.
* Other basses with near-identical Ibanez electronics are much quieter in the same space
* The bass in question didn't always buzz like this
Maybe a connection to the shielding paint dislodged? The electronics still function as expected and when I take it out of the house they sound as good as ever. But I don't want to show up at a venue with RF issues and have it buzz like this.
So my question: Does this sound like a shielding issue? If I bring it to a pro and have a really good shielding job done, should that protect me from any RF-noisy spaces?
I also seem to be having a problem very similar to OP with several of my Spector Euro basses - all of which are equipped with EMG active pickups (either DC's or TW's). Same symptoms - doesn't go away when not touching the strings and improves depending on how I move my bass. I've done a lot of playing in my recording room and it seems like this has come on somewhat recently. The fact that several basses are affected make me think it is environmental and not the basses. I will say my NS-5XL seems dead quiet, but that does have copper shielding in it. The Euros seem to have some kind of shielding paint in the cavity. I still think it's something in the house, and that the NS-5XL is just better at not picking it up.
I've had all the circuits in my house with CFL's or fluorescent lights off, and I completely turned off any wireless routers or cable modem nearby. The buzz still persists.
It does not get louder when I touch the strings so I don't think it's a grounding issue in the bass. My batteries are fresh and I have tried multiple cables. I even moved to a different room with just my Bass PodXT and headphones and was still picking up a buzz from somewhere.
I know OP was looking into if something is loose with his grounding in the bass, but in my case that is not likely since several basses are affected.
I need to do some more experimenting tonight - I'm going try and take down as many circuits as possible in the house and see what happens.
