So I took my Jazz bass to my local tech today to see what the issue was with my bass. Here's the problem and it's probably been said a thousand times before but anyway.. I had some Model J's installed in my bass a while ago, and everything was fine, nice and quiet, until I took my hand off the strings - buzz (I know you've all heard this before), but the problem only occurs with the bridge pickup . With the neck pickup soloed, even when I take my hand off the strings there's no buzz, but as soon as I roll in the bridge pickup and take my hands off, there's the buzz. So yeah I took it to my tech, and he said that there's no way around this because I'm acting as the earth when I touch the strings or any metal part, and shielding won't make much of a difference. So is all this true or is there actually a problem to be fixed here? Thanks in advance!
