man
i have played live like twenty times and always the soundman is a mother****er, they don't know anything and they don't help.
Wow, 20 gigs and 20 bad sound guys. With odds like that maybe you need to buy a lottery ticket real quick.
I can't even say that I've ever encountered that high a percentage of a-hole guitarists. Maybe a dozen or two out of a couple thousand. Hardly a home run.
Well, as a pro sound guy for a lot of years let me give you a little insight into the touring world from our perspective. I think it matches up well with what some of the pro players here have experienced as well.
1. Do unto the sound guy as you would like him/her to do unto you. If you are an ass to him, don't expect a boquet of roses in return.
2. Play appropriately for the room, the band and the audience. If you dominate the band's volume, everybody will struggle all night, your band mates included.
3. If you want to play at the venue again, think twice before opening your mouth to the sound guy. Generally their advice to the booker is going to be listened to, especially if youy don't draw big numbers.
4. Don't damage anybody else's equipment... they may be bigger and meaner than you expected.
5. Don't ever start a fight that you are not prepared to finish, the crew are generally pretty friendly with security and security watches their backs. In fact, I saw an incident happen (names not mentioned) where a tour manager (a pretty big guy) who had a reputation of being a real prick was in an "insane rage" and took a swing at the crew chief at a "large" show. He connected and went to kick the guy on the ground when one of the other hands hit him over the head with a 2x4. They had to do CPR, called the paramedics and off he went to the hospital for surgery to remove broken bone from his brain. His touring career is over. It was determined to be self defense, the crew chief had a broken jaw and had the tour manager kicked him, could have really hurt him a lot worse. This leads me into the next "rule"
6. No drugs at gigs. Ever. Not appropriate, and can lead to irrational, uncontrollable behavour as in 5 above (yes, drugs played a big part). In the early 80's there was a good up and coming band that was signed to RCA, their first album was quite successful with one hit. Everything was going well until they got busted for drug(s). Game over.
7. Drink responsibly... nobody wants to deal with a loud, obnoxous, abusive musician. If you can not handle your alcohol, don't drink.
8. If you travel internationally, be sure all your paperwork is in order, don't carry drugs and don't do anything to get your band in trouble in another country. You may find that you are prohibited from re-entry in the future (if they don't throw you in their version of jail first).
9. Respect your bandmates and play with them as a group, not as an individual. If you agreed to play a bass line in a particular style because that's what the band decides, play it that way and not the way you WANT to play it.
10. Recognize that nobody is out to get you, and that most sound guys are really nice guys, who do their jobs well and can make you sound either better OR worse than you really are. Just depends on how you treat them.
Hope this helps.
