There have been several threads where sound guys have been bashed into the ground. Granted, I have issues with them sometimes too, but I think there needs to be a pro-sound dude thread! We need to learn how to cooperate with sound guys to make their truly hard job much easier. Think about it, they have to mix the sound, then adjust it to where you, the guitarist, the drummer, whoever else is in the band, the audience, and himself are ALL satisfied with the mix! They have to put up with all the complaints from the band needing more volume in their monitors, get more presence onstage, etc. At the end of the day, it's a wonder that there are even sound guys left in the world. To me, the key is striving WITH them to solve problems. Think with a bit of creativity. Try to work out the problem. And before all that, a very wise bassist once advised to go up at the beginning of a gig, before you even work with him, and introduce yourself, shake his hand, tell him about the band, the way you guys like the mix, what effects you guys use, etc.
