Hello! My Squier Jazz Fretless bass has been a beautiful instrument, I love it dearly.. But just today, I turned on my amp and I get no sound from it.. It was working about and hour earlier just fine! But now nothing!! I've tested it in a few other output devices, I'm fairly sure it's the bass, not the amp. I SHOULD MENTION: The jack has been loose since I got it, but I've been very very careful with it, but I'm sure that has something to do with it. (I've had no other problems with it until now, no crackling, buzzing, etc.) But now, completely dead! I'm a complete noob to the wirings and setup of a bass, but I'd really like some suggestions. Thanks a lot! EDIT: fail on my part, this is going to have to go into the pickups/electronics forum, sorry!
