Ok I'm not very smart when it comes to the whole technical side of my bass but about 2 days ago my bass fell on the floor like slid off the side of my closet (i know i was stupid). Anyways when i plugged it into the amp it had a very bad connection like ifi moved around the connection to the amp got cut off or if i leaned a certain way it would also cut off. Can someone tell me what the problem is? And is it dear to repair cause i have a gig in a weeks time.
