Even though this happened at Church service this has to have happened to somebody else at sometime and somewhere. We start playing and while playing we all hear this high pitched sound as if someone is hitting the highest key on the keyboard. All are looking around like, what is that(and we should've just stopped to figure it out) and kept playing. It went on for the first two songs. And it wasn't continuous, it came and went. I thought my bass was vibrating something in such a weird way it was creating some odd harmonic. You could see the uneasiness on everybody there. It was just horrid. Finally after the 2nd song our guitar player had figured out it was his guitar. The high E string had snagged itself up under a fret and when he played it that would create that sound. Anyone here have anything similar happen?
