Hey, folks I have this weird overtone thing going on with my open E on my '09 Am Std Jazz. Guy I know told me to string it through-body next time, did that didn't work. It's with all the pick-up configs. Guy also told it could be the chrome covers on my bass. But it still makes the overtones with them off. Unplugged it seems to be there, too. Albeit more subtle. So... String or bass issue?
