Alright here's the deal: I just bought a used Zon. I didn't notice it when I sat down and played, but when I played standing earlier I noticed something strange. Whenever the plug moved in the jack (even slight movements on the order of a few millimeters), the signal would cut out and I would get that evil popping sound. I don't think it's the cable because it doesn't do the same thing with any of my other basses. So, is this most certainly a jack problem? Is it easy to find and install a new jack? I don't know of any techs in the area, and I'd rather not have to send the bass back to Zon for something that seems so minor. Thanks a ton!
