Haha, I wrote a song that includes the word "hell." Some of these little old ladies around here like the song but won't say "Hell." So, at my concert next weekend, at which I will be playing acoustic guitar, I was thinking of having a recruit BLEEP in another mic when I sing the word "hell." They could vocally do it and that could work if they have a good BLEEP but, if their BLEEP sucks...

What kind of electronic alternatives do I have? Anyone got a BLEEP.wav? I wonder how I could do that and him push the button on something so that it would be instantaneous output? Timing has to be close to spot on.
