Ok, so I searched and could not find the answer for this. In my garage i normally get some buzz, but with my new j bass, the hum starts when I touch it. What kind of issue is that? And yes, I turned both pickups to full, but that did nothing. Normally when you touch a bass with poor grounding hum stops, and I don't have ground issues in other power sources (practice space) with this bass or my amp.
