I recently got a new Squier VM Jaguar bass (the one with stacked knobs) and have been loving it so far. But something strange happened just a few minutes ago. The tone knob for the neck pickup now moves freely, you can spin it around and around and it will never stop. I have treated this bass like a baby and haven't banged it against a wall or anything like that. I have had it for three days now. ***? So, any ideas about how this could have happened and how it can be fixed?
