Years ago a strap gave way and the body of my beloved Variax Bass hit the floor. Not too hard but any is too much. I'm pretty sure the next time I plugged it in, it did not work. It was years ago but i'm pretty sure the drop did it. I just set my gear up and tried it again in case I overlooked something. Still no sound, Just a green light on the bass and xps-DI. Is there something easy that may have come loose that I can spot and fix inside? If not, who can repair this for me in NYC please?
