My bass has always buzzed but now that I have a new rig, it's really noticeable. It's an active MIA Fender J-Bass and the buzzing is LOUD. It quiets down quite a bit when I touch any metal part of the bass such as the bridge, strings, or tuners, but comes right back when I take my hands off. So far I've stripped more plastic off the ground wire under the bridge to make better contact and I soldered a new wire from the input jack to the main circuit board. Same thing. In it's current state, the bass is unusable and I'd really like some advice on how I can get rid of this buzzing. FYI: My passive MIA Fender P-Bass does not buzz at all. Thanks in advance for any advice.
