So...I played outside today at a farmers market. The show went well for the most part. I was going through a 15w Beringer mixer-amp (an acoustic guitar amp with a vocal input and channel on it.) Then, in the middle of a song I hear out of the speaker: "...he's not doing too good. I wonder if he will strike out."

The amp had picked up a ball game.

I treated it like feedback (potted down, unplugged and re-plugged etc.) and it went away for awhile. But I've never heard of this. I must have created an antenna somehow.

Geez, I have enough issues without my amp making smart remarks, ya know?
