I've been moving my Crate BX100 about a lot recently, and today i started to lose sound during playing. It seems the positive and negative wires coming from the cab going to the head are the issue. Whenever the black thing they go through (not sure how else to describe it, its on the underside of the head) isnt pressed down (well, technically up) with a lot of pressure, the sound shakes, and then dies. I figure its a matter of loose wires, probably fixed by delving into the head and reconnecting/sodering/something else. Just how dangerous a move is this for me to perform?
