245 Replies and only 2 (I think) mentioned wireless and "running around like maniacs"... I suppose it depends on the music.
In my recollection, I have almost always had my rig set up on the drummer's right -- and that's my "home" position, BUT, I am wireless. I move around the room to hear the best mix -- Sometimes, I'm directing the sound guy or I AM the sound guy). In one case, when my band covers "All Right Now" by Free, which only has bass during the chorus and the bass "solo", I go out into the audience and watch the band perform the verse. I find this kind of behavior is often very well received, at least in a rock 'n' roll type context.
