Hi, I'm a newbie here. Just joined today on the hopes of getting this problems fixed. I bought a used MIM P Bass recently. Worked fine, but there was a buzzing sound. The buzz would persist until I touched the strings or the bridge. I did a little research and came to the conclusion that it was a grounding problem. Then, I bought some copper tape. Stuck it in all the crevices very neatly so that now every hole in the body was coated with this magical stuff. Then, I put everything back into place, slapped on some new strings, and proceeded to jam out on my new rig... What! No sound came out. Not a buzz! (which relieved me, but still) There was nothing coming out. I tried playing some Jamiroquai to funk it out, but nothing! Can someone help me out? What could I be doing wrong?
