Yesterday, I was in the middle of sound check before service when I suddenly lost volume. Immediately I thought that I needed to change my battery so I did. Well, with a new battery installed, I began to play and my volume dropped again, until I touched my volume pot, which lead me to know that something wasn't grounded. Low and behold, my ground wire had popped off. On this sunday, I left my backup bass home and my normal bass player left both of his basses home because we were switching on this Sunday. So I had to play the churches bass that had strings the age of Moses on them. Has anyone else had something similar like this to happen to them during or before a service/show?
