I have an Ibanez SR505 that has been buzzing pretty badly at my house. I believe it's RF interference because ground lifting and completely isolating from the power grid make no difference. Also, changing the way that I'm facing can limit or almost totally remove the buzzing. Sounds like classic RF interference to me. 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? Thanks!
